SOLD: PRIMARY WEAPONS - MK109 PRO UPPER RECEIVER COMPLETE 300 BLACKOUT 9.75" BARREL

*************Sold on another Forum*************

Excellent+ condition. I bought this new a year or two ago and maybe put 50 rounds through it. A2 FH has been replaced with a Sig 3 prong.
$650 Shipped. PP, M/O, Zelle, Bank/Cashiers Check. Shipped only, no local pick-up.

The Primary Weapons System long-stroke gas-piston upper receiver is one of the more-innovative developments to hit the AR-15 market in recent years, and now, you can get your hands on a unique variant of this system straight from Brownells! The PWS MK109 PRO upper receiver chambered in 300 Blackout contains everything you need to get your AR-15 set up right.

Of course, this system features the unique, long-stroke system that Primary Weapons Systems upper receivers are known for, plus this system includes a few extras that make it a must-have! The PWS upper is a complete system, so you'll get a bolt-carrier group, as well as a Radian Weapons Raptor charging handle.

Barrel length: 9.75 inches
Overall length: 18.5 inches
Weight: 3 pounds, 10 ounces
All-black finish
Other features found in the PWS MK109 PRO upper receiver include a free-float, M-LOK handguard, an adjustable gas system and a short barrel equipped with an optimized 1:8-inch twist rate.
