Primary Weapons Systems MK107 MOD 2-M 7.62x39 Complete AR-15 Upper - 3-Setting Adjustable Gas System - 7.75"

The Primary Weapon Systems Mk107 MOD 2-M 7.62x39 Complete Upper is the heart of your AR style rifle or pistol. If you’re looking for a great option around which to build an AR in 7.62x39mm, this is one of the best options on the market today. This is a complete upper that includes the receiver, barrel, muzzle device, handguard, and all of the accessories that you’d need to go to the range today as long as you have a compatible lower.

Features:

• 7.75” barrel
• 1:10 twist rate
• 7.62x39 caliber
• PWS Long Stroke Piston System
• CQB30 Muzzle Device
• Radian Raptor Charging Handle
• Has Ejection Port Cover

This upper is perfect for people looking to build an AR pistol or short barreled rifle in the same caliber as the AK47 family of rifles. This includes nearly everything you need and can simply be popped on a lower as is. While this would technically function, we do highly recommend adding a sighting system of some sort to this upper once it is attached. The premium parts, from the charging handle to the handguard and muzzle brake make this an excellent option for those looking for a new AR build.
