Once upon a time, a "dissipator" AR was created by taking a 20" rifle-length gas system upper and cutting the barrel down to 16".  This allowed the shooter to keep the long sight radius of a rifle for accuracy, but keep the carbine length barrel for maneuverability.  The proximity of the gas port to the muzzle, however, played havoc with timing and made reliability a hit or miss proposition.   Advances in AR technology  have produced reliable carbine and mid-length gas systems, that can be hidden using low-profile gas blocks.  This allows for a front sight base to be pinned in the rifle position for the longer sight radius without the worry of the unorthodox gas port location affecting operation.   We use the term "mock" to differentiate our dissipator from a cut-down rifle length version.

Our Hammer-Forged Mid-length dissipator uses a "Machine Gun Steel" barrel that is thick chrome-lined for durability and high pressure tested and magnetic particle inspected.

Barrel:  A proprietary blend of Hammer forged chrome molly vanadium made by FN that is referred to as "Machine Gun Steel" by virtue of its use in FN's M249 and M240 weapons.   The hammer forging process work hardens the steel, making it more durable.  In addition, the chrome process for the bore allows for a lining almost twice as thick as a standard M16 for enhanced durability.  Chambered in 5.56 NATO, with a 1/7 twist, M4 barrel extension, and a Mid-length gas system.   A2 style profile barrel is Mil-spec phosphate coated, High Pressure tested and Magnetic Particle inspected.  Barrel is finished off with a pinned F-marked front sight post in the Rifle position with sling swivel,  rifle length handguards, and an A2 flash hider.

Upper: Forged 7075-T6 A3 AR upper is made to MIL-SPECS and hard coat anodized black for durability. Featuring machined T marks, and a mil-spec finish. These uppers are made for us right here in the USA by a mil-spec manufacturer.

Each upper is assembled to order with care, and test fired.  Bolt carrier group and charging handle not included.

Great
Fast shipping ( ordered Saturday arrived weds).
Great quality. All parts are mated well to the barrel- no room between the FSB and the barrel. Finish is phosphate- typical ar finish. Great quality all around and good price.

Nicely done
Decided to get one during Father's Day sale. $299 with rifle length sights. AND cold hammer forged barrel by FN. Can't loose on that. Was on the fence about getting 3 but only got one. Bad idea. As soon as I placed my order I went back to get 2 more and out of stock. Phooey! Put a carry handle on it a Spike's BCG and BCM Gunfighter CH I had in the safe and borrowed the lower off my Rock River to zero it in. First five rounds were one inch high and two inches left. At 50 yards. Nice. The grouping was about 3" but I can't see like I used to. So at 50 yards your guess is as good as mine as to where the center of the target is. I usually use optics of some sort. At least a 3x. But I wanted an AR with rifle length sights for the long sight radius so I could build one gun not dependent on batteries or optics. Plus the midlength gas gives the rifle manners. No worse than dad's old Ruger 10/22. And it's much more reliable than some of the dissipators out there running rifle length gas on a 16" barrel. One neat bonus with a carry handle it resembles an M16. So I built a lower with an A2 fixed length stock to really give it the look. Besides most people don't know an M16 has a 20" barrel anyway. I would have bought 7 more by now for my daughters but their never in stock. Get them when you can! Oh yeah one small issue was the A2 birdcage flash hider was loose when it arrived. Not a big issue. I have the tools so I tightened it and "timed" it in five minutes. I'm sure a gunsmith would have done it for next to nothing.
