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. 😜

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.

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.

More news on the release of these products is expected in the next few weeks.

Adams Arms Press Release

Established in 2007, Adams Arms began with an innovative design that improved the operating system of AR style rifles. The Adams Arms Retrofit Kit provided users the ability to upgrade their existing direct impingement rifles to a piston operated system in a mere thirty minutes or less using a 3/4 inch wrench and hammer. They received a patent in 2008 and gained major OEM partnerships which quickly made their system the number one piston system on the market with more than three times the OEM contracts of competitors.

By 2011 they were building their own upper assemblies and within a year manufacturing complete rifles. Adams Arms’ growth skyrocketed as they acquired their largest OEM manufacturer allowing them to produce the majority of their parts in-house. Adams Arms also develops and utilizes some of the most technologically advanced manufacturing processes, machining techniques and coatings, including QPQ, PVDs and Nickels, that far exceed Mil-Spec standards for quality and performance.

They launched VooDoo Innovations, a sister company, in 2013. VooDoo brings high end coatings and processes to the direct impingement market. With so much growth, a major decision was made to purchase $4 million in manufacturing assets. New equipment and the addition of key leadership and industry hires resulted in more than 75% of production moving in-house. Distribution channels were expanded to new distributors, buying groups, direct dealers and website retail sales.

This year they have continued to streamline production and grow their line with products such as:
–  XLP Low Profile Gas Block
–  C.O.R. Rifle
–  Ultra Lite Advanced Dissipator
–  Line of 300 BLK Products
–  VooDoo Rail System
–  VooDoo Innovations LifeCoat Parts

Rainier Arms recently launched a line of complete Piston AR-15 Uppers that they have hand built using their high quality Rainier Arms parts and Adams Arms Mid Length Piston kits. I know what you’re thinking because I thought it too. “Oh great. Another expensive Piston upper”. Thankfully that is not the case.

Rainier Arms Force Piston Upper

The Rainier Arms Piston Series uppers all feature the new VooDoo Innovations Melonite coated barrels, Rainier Arms Compensator (RAC), Rainier Arms Milspec upper and the Adams Arms Complete Piston Kit including BCG and Charging Handle. They are offering two models, the Base and the Force. Both models come in your choice of 14.5″ and 16″ lengths. The Base is exactly what you would assume, a more basic upper with standard plastic hand guards. The Force model upgrades to one of the brand new Rainier Arms Force KeyMod rails. 

Base Piston 5.56 Uppers in both 14.5″ and 16″ models are priced at just $575 each. The upgrade to a Rainier Arms Force KeyMod rail only costs another $120. Check out the pictures and details below. If I were had some extra funds for a new upper this would definitely be at the top of the list. Links to purchase are listed below. Get on it before everyone finds out about these and they sell out.

To say that I want an ARAK-21 upper from Faxon Firearms is quite the understatement. The ARAK-21 is a Piston Driven upper receiver that fits any mil-spec AR15 lower receiver. You might be asking yourself, “What’s the big deal?” but there are many differences between the ARAK-21 and your normal AR15 Piston upper. Most Piston uppers require the use of a Buffer Tube, Buffer and Buffer Spring. They would also typically require the use of a rear charging handle. The ARAK-21’s self contained design means you don’t need any of that. When the weapon is fired the bolt travels inside the upper and never exits the rear of the upper like an AR15 which opens up so many possibilities for finishing off your build. The ARAK-21 features a monolithic style handguard/rail system and has a non-reciprocating forward mounted Side Charging Handle that can be swapped to either side. Basically, if you took the best parts of an AK, SCAR and AR15 and created one complete upper you would have the ARAK-21 upper. This may very well be my next upper. I’m liking it more and more as I watch the video and look at the pics below that my good friends at Defense Marketing Group put together. Check it out!
