CPWSA 14.5" Ultimate Carbine Upper

CPWSA 14.5" Ultimate Carbine Upper

This is our new 14.5" barrel/16.5" overall length upper package. Features a JP Enterprises upper receiver, Syrac Ordnance Generation II adjustable gas block, Lantac Dragon Advanced Muzzle Brake, and Viking Tactics 13" Alpha handguard. Does not include bolt carrier group or charging handle. Note: picture shows a JP polished stainless low mass bolt carrier group and Raptor charging handle.  We have bolt carrier groups and charging handles which can be purchased separately.  

If you've been wanting a 14.5" barrel AR15 upper 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" barrel offering, had it professionally cut down to 14.5", re-threaded, re-crowned, and had a Lantac Dragon Advanced Muzzle Brake permanently attached. 

As per ATF Handbook Chapter 2, we have done all the work for you to ensure these barrels meet the 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)

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, with 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; and the chamber and 1 in 9 twist rate allows shooters to use standard XM193 or other readily available 55 gr. ball ammunition.
