CPWSA Ops Inc 14.5″ AR15 Barrel Package


2 in stock


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 an Ops Inc muzzle brake permanently attached.

This is a 14.5″ barrel/16″ overall length barrel/muzzle brake package. Features a Syrac Ordnance adjustable gas block, Ops Inc R3E2C Muzzle Brake, and standard star barrel nut. Both the muzzle brake and the adjustable gas block have been bead blasted to a nice matte finish.

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″ long including permanently affixed Ops Inc 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.

Note: barrels should be installed by a competent gunsmith and checked for proper headspace. Failure to do so can result in firearm damage, personal injury, or death.
