As you can see I went for a pretty lightweight KISS style rifle. I don’t really like to just haphazardly throw a build together. That’s one thing I always tell people who are building a rifle. Think through and figure out what you want your rifle to be. I have plenty of “overweight” rifles so from the start I planned on keeping this one fairly light. This build came in at only 6 lbs. 12 oz. which for a billet upper and lower set is pretty good. To do that I utilized some lightweight accessories which includes a Fortis Manufacturing REV 12″ rail, Magpul K grip and MBUS, Seekins Precision T-1 mount and B5 Systems SOPMOD Bravo stock and QD End Plate. Other parts that aren’t necessarily lightweight but were used are the Smith Enterprise Vortex flash hider, CIV Tactical 16″ M4 barrel and BCG, Impact Weapons Handstop, ALG Defense ACT Trigger, Battle Arms Development BAD-ASS selector, BCM Low Profile Gas Block and a Receiver Extension Kit from Damage Industries. Any questions or comments regarding this build? Shoot me an email HERE.

This is a sneak peek at the new CMT Tactical UPUR-1 billet AR15 upper receiver. I was fortunate enough to get my hands on one a bit early and man are these nice. Super clean lines, great finish. I have all the parts to finish off this upper and plan on doing it this weekend. These uppers will be available for purchase starting Monday. For now, due to just getting this upper last night, I took some quick shots with my iPhone that actually turned out not too bad for what they are. I’ll get this upper built and take some real pics of it to share with you on Monday.

CMT Tactical UPUR-1 Billet Upper 1 620

The Cross Machine Tool Ultra Precision Upper Receiver Part# UPUR-1 is the perfect Mate to your UHP-15 lower receiver or would also be a great match with any Mil-Spec lower. The UPUR-1 is machined from Billet 7075 T6 Aluminum unlike the more commonly used 6061. Using the 7075 T6 aluminum gives the UP-UR a 65% increase in strength & rigidity over 6061 aluminum receivers. The UPUR-1 is machined on a 5 Axis machining Center to reduce the number of operations/setups required to complete. This machining process allows the highest possible accuracy to be obtained over the traditional 3 or 4 Axis machining method. The UPUR-1 is designed for increased function, performance & to provide an advanced modern appearance & feel to the AR15 platform weapon system.

CMT Tactical UPUR-1 Billet Upper 1 620

Expect the new CMT Tactical UPUR-1 billet AR15 upper receiver to go on sale Monday (7-15-2013) with an MSRP of just $209.95. I’ve heard through the grapevine that Rainier Arms will be selling the initial run of lowers at a special introductory price so you’ll definitely want to keep tabs on the CMT Tactical “Manufacturer” Page at And if you really want to be prepared, Rainier Arms has the CMT Tactical UHP-15 billet lower in-stock at the before mentioned link.

Faxon Firearms ARAK-21 Complete Upper

Posted on July 11th, 2013 by ar15news

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!

NEW!! AERO Precision Now Offering Cerakoted AR15 Receivers

Posted on July 8th, 2013 by ar15news

AERO Precision has very recently started offering all of their AR15 receivers Cerakoted in both Desert and Olive colors. According to AERO, the colors are designed to match as close to Magpul colors as possible. The Desert color would be similar to the Magpul FDE and the Olive would be a good match to Magpul OD Green. The cool part is you can now get this on all of their receivers including the popular COP Uppers. There’s not really much by way of specs or details other than to say that these are the same as their usual high quality mil-spec receivers just offered in something other than Black.

**4th Of July 2013 Sale** DIY Armory 80% Lowers

Posted on July 2nd, 2013 by ar15news

The guys over at just received their latest shipment of 80% lowers and these look like the nicest ones I’ve seen to date. They are all on sale right now through July 13th at midnight. There has been a huge explosion in the popularity of 80% lowers lately. I would venture to say there are thousands of people right now that have ordered 80% lowers from Crowd Funding Campaigns promising lowers for ridiculous prices. These customers still have not received them for one reason/excuse or another. That is not the case with All of their lowers are in-stock and ready to ship and were actually produced by one of the largest forges in the U.S. These new lowers also feature grip serrations on the front of the magwell and also have the Safe and Fire selector symbols already etched in so that is one less thing for you to have to do. Many people think the benefit of buying an 80% lower is to save money but in actuality you probably won’t save any money. The real benefit is to have a non-serialized lower that only you know about. Get yours at and get yours way before those other guys will. Details are listed below.

As always:

-7075 t6 forged lowers

-Flared and 100% Broached mag wells

-Mil Spec

-Type 3 anodizing

-Made in the USA

Some of the new features on the lowers which we are really excited about and we think make these the best 80% lowers on the market are.

New features:

-Grips have been milled out on the mag well for increased stability when firing.

-A screw hole has been added so a torsion screw can be inserted (screw not included) for increased stability   between the upper and lower.

-We have etched in fire and safe logo’s for customer convenience and savings

Also, if the Facebook Page reaches 25k fans by the end of the month (which would be a huge feat) they will be giving away a lower build kit which includes one 880% lower, one LPK and one Buttstock and Buffer Tube Kit. Make sure you like their page to qualify.
