A good majority of 300BLK ARs are build as either an SBR or AR Pistol and a good majority of those builds are also purpose built to be run suppressed so its safe to say they get their fair share of abuse. KAK Industry just introduced their new Cold Hammer Forged 300BLK barrels or as they call them “The Ultimate 300BLK Barrels”. The new CHF 300BLK barrels are all 41V50 Steel with Concentric Threads for perfect suppressor alignment, Melonite Finish inside and out, Pistol Length Gas and available in your choice of 8″ or 9″ lengths. And at just $180 it’s hard to beat!

After quite a long time out of stock, Ballistic Advantage 5.45×39 barrels are finally back in stock. 5.45×39 is the ammo that you usually shoot out of an AK-74 and for a long time was some of the cheapest centerfire rifle ammo around. If you’re like me you stocked up on it when you could and now need a good barrel to shoot it all. The Ballistic Advantage 5.45×39 barrels are some of the nicest you’ll find anywhere, are very accurate and are machined from 4150 Chrome Moly Vanadium steel with a QPQ Corrosion Resistant Finish. Ballistic Advantage also includes a WOLF Extra Power Hammer Spring to ensure proper function. They also have 5.45×39 Bolts available for pre-order as well.

If you’ve followed AR15NEWS for any decent length of time you’ve probably noticed we build lots of ARs. Some times, as an AR builder, it’s easy to get in a rut and kind of build the same thing over and over again which gets boring. All it takes is a bit of imagination and planning and your next build can be the best one you’ve ever put together. This is the very case with my most recent build. 

Believe it or not I had SBR’d this Rainier Arms forged lower well over a year ago but had no idea what I wanted to do with it. Then it came to me and I couldn’t stop thinking about it. From there it was just a matter of time before I had the parts in hand and ready to build.

Lets start out with a few closer shots. From this angle you can see the Rainier Arms ambi safety, Juggernaut Tactical ambi charging handle and Scalarworks OPS (On Point Sights) fixed rear sight.

Rainier Arms SBR Build 1 - Scalarworks OPS Fixed Sights Juggernaut Tactical Ambi Charging Handle - Rainier Arms Ambi Safety

As I mentioned above, this build got started as a Rainier Arms Forged A-DAC lower that I bought and Form 1’d just before the ATF41P effective date. I added a Rainier Arms forged upper and ambi safety, CMC Triggers Flat 3.5lb Trigger and LPK, Superlative Arms Piston Kit, Juggernaut Tactical ambi charging handle, Geissele MK4 rail and Scalarworks OPS Fixed Sights and Low Drag Mount for the Aimpoint T1 and a SureFeed Magazines 20 Round mag.

Rainier Arms SBR Build 2 - CMC Triggers Flat Trigger Geissele SMR MK4 rail Scalarworks OPS Fixed Sights Aimpoint Micro T1 Rainier Arms A-DAC

Of course as a Rainier Arms SBR build I chose to use their 10.5″ .223 Wylde barrel. Covered it with a Geissele MK4 rail, Arisaka Defense 300/IR Series Scout Light and Inline Scout Mount, SureFire SR07 switch, Scalarworks OPS Fixed Front Sight, Magpul vertical grip and Griffin Armament Taper Mount Supresspr Mount. The Superlative Arms Piston Kit gas block is under there somewhere. 😜

Rainier Arms SBR Build - Geissele SMR MK4 - Arisaka Inline Scout Light Mount 300 Series Scalarworks OPS Front Fixed Sight magpul vertical grip Surefire SR07

Here’s another angle of the business end on the new Rainier Arms SBR build. From this angle you can now see how accessible the Superlative Arms Piston Kit gas block is under the rail. This isn’t like many piston kits were you have one or two settings. Its more like a Piston Kit that has a built in fully adjustable gas block so you can really tune it in.

Rainier Arms SBR Build - Superlative Arms - Rainier Arms - Geissele - Scalarworks - Magpul = Arisaka Rainier Arms

This next shot gives you a better idea of how tidy things are on this build. It’s got everything I need and nothing I don’t. The Scalarworks OPS fixed sights and mount for the Aimpoint T1 are absolutely amazing. 

Rainier Arms SBR Build - rainier arms = cmc triggers = scalarworks = aimpoint t1 - juggernaut tactical - magpul - geissele

And here it is. Hope you guys enjoyed a pretty detailed look at my new Rainier Arms SBR build. In the end, this SBR turned out even better than I had pictured it but the initial imagination and passion to create another gun is what got it all started. Don’t be in too much of a hurry to just slap together the first complete rifle you can. Take your time with your next build, map it out, think about what would make you smile every time you see it and then build that. 

Rainier Arms SBR Build - rainier arms - geissele - cmc triggers - magpul - scalarworks - griffin armament - surefire = superlative arms piston kit - aimpoint juggernaut tactical

Here’s the full run down of parts for this build. If you want to copy it, be my guest. Would make for a great AR Pistol build too.  

Already had a chance to get the gas dialed in on the piston kit and man this thing is smooth. Will be getting some range time this week with this gun getting it sighted in. Will let you guys know how it runs soon.

KAK Industry manufactures barrels for some of the biggest name retailers out there and every once in a while ends up with a few barrels left over after a large production run. Right now he’s sitting on some 10.5″ 9mm barrels that he produced for PSA and is blowing them out at an amazing price of just $65. If you’re starting a new 9mm build or just want to build an extra cheap upper for your 9mm PCC, this is a no-brainer.

**Updated image after press release below** Have you ever wished you could run a Rifle Length Gas System on a 16″ or shorter barrel? How about a Carbine Length Gas System on a barrel shorter than 10.3″? Typically, the longer the gas system the smoother and softer the recoil impulse will be. It’s been tried many times before and the end result has always been either an extremely oversized gas port OR scrapping the common length gas system and switching to a custom length gas system….that is until now. My buddy Garret at SPECIAL OPS TACTICAL is today introducing their PATENT PENDING Siphon AGP (Angled Gas Port) Nitride Barrels. By creating an angled gas port they were able to run longer gas systems on shorter barrels than ever before. The crazy part is they are using regular gas blocks and regular Pistol, Carbine and Rifle length gas tubes so the only custom part is the barrel. Does this have you intrigued like it does me? Tons of information is available below. Check it out!

[Press Release Begins]

In a quest to design, engineer and produce the World’s shortest length gas operated firearm barrels using industry standard high quality components Garrett Potter owner of Special Ops Tactical an Embry Riddle Aerospace grad, Philip Picardat owner of Artisan Arms /Micro MOA a Master toolmaker who has made high precision barrels for the industry’s biggest names for over a decade and his son Ryan McCormick collaborated efforts to produce an all new revolutionary line of barrels called “The SOT Siphon AGP Barrels”.  This new revolutionary line of barrels are being produced by Artisan Arms and will be exclusively sold by Special Ops Tactical.  We have developed and manufactured the first and only barrels ever to feature a “rearward” angled gas port in order to increase dwell time and gas pressure enabling us to create the shortest “Pistol length, Carbine length, Midlength, Intermediate and Rifle length barrels in the World while utilizing non-proprietary “gas tubes and gas blocks” by way of our all new “Siphon AGP Barrels” that feature our “Rearward” angled gas port.   Until now no other company in the world has produced a barrel that features a “Rearward” angled gas port. “Meaning from the top of the barrel where the port is initially drilled with the gas port angling rearward back toward the “barrel extension” / rear of the barrel in order to gain dwell time and gas pressure”.  PATENT PENDING)

Special Ops Tactical Siphon AGP Nitride Barrel 1

Traditionally and to date all barrels are drilled with a straight 90 degree  gas port and require about 1.5” Inches of barrel in front of the gas port in order for a barrel to function properly.  Otherwise you end up with a gas port so large that in order to cycle the system that the bolt carrier group is violently slung back by the over gassed port “vastly” outside the area of “normal” operation that even a muzzle brake is not able to overcome the extreme over gassing of the enlarged straight port which leads into several negatives being accuracy, recoil, wear and tear and multiple reliability issues; Not to mention the extreme deafening sound when using a muzzle brake on a short barrel.   Our new “Siphon AGP Barrels” cycle the gas system properly with a much smaller gas port allowing for correct, positive and ultra-reliable function as well as increased recoil reduction “because of the smaller port “which provides much better recoil control as well as accuracy that is just NOT possible with all other manufacturers’ barrels to date!

Our new revolutionary design allows our barrels to be “the shortest” possible length while using  standard gas tubes, standard gas blocks as well as greatly reduced sizes in gas ports because of their Patent Pending “rearward” angled siphon gas ports.  Our new “Siphon Angled Gas Port” is so much smaller than traditionally possible generally speaking the Siphon AGP gas port sizes are 10 to 20 thousandths smaller than their straight port counter parts.  The new Siphon AGP barrels have anywhere from a 8% up to 20% less felt recoil over their straight 90 degree port counterparts depending on specific barrel length, accomplished without the aid of a muzzle brake or any other recoil reducing device!  When a muzzle brake is implemented these barrels are incredibly smooth!

We like to push the limits of what is possible just to see what can achieved.  Designing and building standard components is still enjoyable but we thrive on designing and manufacturing tomorrow’s products!

Throughout this endeavor we knew that there had to be a few key features:

#1. The Barrels must use a standard length gas tubes not custom or proprietary.

#2. The Barrels must use a standard diameter and height gas blocks not custom or proprietary.

#3. The Barrels must be reliable enough to be employed by LEO, Military application, as well as contracted applications.

From our extensive testing we have found extremely promising results that the Siphon AGP barrels have much less of a recoil impulse than their traditional “Straight Gas Port” counterparts.  Generally speaking  8% up to a 20% reduction as compared to their straight port counterparts partially due to the reduced gas port size but is also associated with being able to run a longer gas tube not previously possible with traditional straight port barrels but also because the gas flow has one less 90 degree change in direction so makes the flow of gasses smoother throughout the entire system.

The profile, shape and weight of these new barrels was also very important to us.  We chose to start with a medium contour custom profile on this new line of barrels because of their crossover ability of being able to deliver excellent accuracy but in a more balanced refined lighter weight profile than a traditional government profile as well in efforts to help overcome barrel flex and whip.

Many manufacturers across the board intentionally over gas their barrels in order to ensure their barrels cycle on all types of ammo being hot or light loads.  This causes excessive wear and tear on the entire system and its parts as well as causing unwanted excessive recoil.   We make sure our barrels are not over gassed.  I see and hear so many people both customers as well as others in the industry state or think that a specific gas port size for a particular barrel length and or profile will be “universal” the same or similar to every barrel made across the board; this is NOT the case!  The gas port size has a “direct” relationship to the length of barrel and the Inner diameter of a barrels bore and the slightest change or difference in bore diameter will determine the proper gas port size. (Even with barrels of the same length and caliber all bores are not the exact same size.)

After extensive testing I have realized we have truly designed and manufactured “unobtainium”.  This is the only actual dissipator barrel system.  The new guns “That feature our SOT AGP Siphon Barrels” are truly very special and unique.  They will become a staple in the industry because of their unparalleled smoothness and reduction in recoil that can be applied to Military, Law Enforcement, Contractors and recreational shooters alike.  Our shortest 5” Inch AGP Siphon barrel offers a super compact firearm that is lightweight and extremely agile with such a major gain in recoil reduction over its 7.5 inch straight gas port counterpart, as well as being able to have extreme muzzle control in both semi and full auto modes of firing.  To the shooter the guns that feature our SOT AGP Siphon barrels are so much smoother than any other AR15 platform weapon in or near its category and will absolutely be a major game changer for the industry and shooters alike.  As soon as people get a chance to fire this barrel they will instantly feel and see that this is truly a revolutionary product!

Special Ops Tactical will be first releasing (5.56 NATO Caliber Siphon AGP Barrels in (5”Inch Pistol Length Gas),( 9”Inch Carbine Length Gas), (14”Inch Rifle Length Gas) and (16.01”Inch Rifle Length Gas), as well as several lines of our new Patent Pending SOT Siphon AGP barrels in multiple lengths and calibers including (5.56, 300BLKOUT, 7.62×51, 6.5 Creedmoor) as well as Complete Uppers and Rifles and will continue to add more lengths and calibers in the future so please stay tuned!

The image below better shows the “rearward” angle of the gas port. Unlike some older AKs and a few other AR manufacturers that have made angled gas ports drilled towards the muzzle end of the barrel, the SOT Siphon AGP barrels angle “rearward” towards the barrel extension.

These days everyone builds their own AR and for good reason…its a ton of fun, can save you money and gives you good knowledge of how an AR works. One issue that many AR builders run into is finding compatibility issues with the parts they bought. With the popularity of ultra low profile handguards one of the most common issues is gas block incompatibility. Many handguards are so low profile that they can actually come in contact with the gas block itself or accessories attached to the handguard. I recently ran into this issue myself and figured I would share my experience with you.

One of my most recent builds is a DMR style rifle with a BSF Barrels 16″ barrel with a Carbon Fiber Shroud. Because of the carbon fiber shroud (designed to strengthen the barrel, reduce weight and help it vent heat) the gas block seat is .936″ so of course I just ordered any old .936″ low pro gas block.

Everything installed just fine, I slid the Cross Machine Tool UHPR Mod 2 handguard over the barrel, tightened it all down and … DUN DUN DUUUUN … the gas block was touching the bottom of the handguard. Not just close, literally touching. That’s called “unfreefloating” your barrel. 😂😂 This is something I verify every time I build a rifle as I’ve also seen MLOK screws touching gas blocks as well. Anything coming in contact with the gas block / barrel can and will effect accuracy even at just 100 yards.

Gas Block Touching CMT rail

In a basic beater build you might not care but in a build like this where accuracy is the goal, you have no other choice than to either swap out the gas block or swap out the handguard. Easiest and cheapest is to swap the gas block. Thankfully Cross Machine Tool has just released their new line of J.A.G. (Just A GasBlock) gas blocks which includes a .936 Gas Block specifically designed to fit under their UHPR handguards and many other super low profile handguards.

**One of the only things I actually do like about .936 gas block seats is that the .936″ opening of the gas block is usually big enough to remove without taking off the muzzle device**

While I had the gas block off I also decided to put a second dimple on the barrel so that the second set screw of the gas block would screw all the way in instead of sticking out just to make sure there was adequate clearance.

At this point it was time to reinstall the CMT handguard and check to see how it fit. Flipped it over and definitely good to go! The new Cross Machine Tool JAG .936 Gas Block did the trick and my barrel is now truly Free Floating.

Only thing left to do now is get this blaster to the range. I’ll have a full review of the BSF Barrels 16″ barrel coming soon. If you’re looking for an affordable low profile gas block you can’t go wrong with the new Cross Machine Tool JAG Gas Blocks.
