CPWSA 14.5" Ultimate Carbine Upper
If you've been wanting a 14.5" barrel AR15 upper with a comp permanently attached for an overall length greater than 16" 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.
This is our 14.5" barrel/16.5" overall length Ultimate Carbine upper. Features a JP Enterprises upper receiver, Syrac Ordnance Generation II adjustable gas block, Lantac Dragon Advanced Muzzle Brake, and Viking Tactics 13" Alpha handguard. Note: upper does not include bolt carrier group or charging handle. They can be added for an additional fee if desired. Price depends on which bolt carrier group and charging handle you want to add. Contact us for pricing if you want to add a BCG and charging handle.
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.
