CPWSA 14.5" AR15 Upper Receiver
If you've been wanting a 14.5" AR15 barrel with a comp permanently attached so you wouldn't have to pay the feds $200 for a tax stamp, then we've saved you a lot of time and trouble. We took our 16" Ultimate Carbine barrel, had it professionally cut down to 14.5", re-threaded, re-crowned, then permanently attached a Lantac Dragon Advanced Muzzle Brake as per ATF guidelines. The end result is an overall length of 16.5" which means you don't have to have a SBR stamp from the ATF.
Features a JP Enterprises adjustable gas block so you can fine tune the gas system to your load and liking. Simply put on your handguard of choice, clip your new upper on your lower and go shoot. Does not include bolt carrier group or charging handle but those are available separately if desired.
Here's some additional specs on the barrel: .875" before the gas block, .750 at the gas block, then .725 to the muzzle. Black phosphate finished, fluted, 16.5" long including permanently affixed Lantac Dragon Advanced Muzzle Brake, mid-length gas, .081" gas port, 1 in 9 twist, with M4 ramps and 5.56 NATO chambered. Fluting both before and after the gas block facilitates cooling and reduces weight. The mid-length gas system softens the recoil impulse over a standard carbine length gas system; the chamber and 1 in 9 twist rate allows shooters to use standard XM193 or other readily available 55 gr. ball ammunition. These barrels usually also shoot Hornady 75 gr. TAP ammo around 1 MOA as well.
As per ATF Handbook Chapter 2, we have done all the work for you to ensure these barrels meet ATF requirements for permanently attached muzzle devices. Measurement of at least 16" is from the closed bolt or breech face, and the comp/brake is attached via the blind pin method with the pin head welded over. (See picture)
