Description
 
The MK107 762X39 MOD2-M Primary Weapons 7.75 inch complete upper receiver features PWS long-stroke piston system, no forward assist, MLOK handguard with integrated Picatinny sections, CQB compensator, adjustable gas block and Radian Raptor charging handle.

Also know as the "Diablo", this is the shortest PWS upper available. For your SBR or pistol build, the MK107 is the best option for a compact weapons platform. As is normal with short-barrel uppers, concussion can be an issue. The factory-mounted close-quarters compensator helps mitigate this by sending the blast forward. Fortress Tactical recommends C-Products Defense 762X39 AR15 magazines for use with this upper.

PWS Diablo Upper!!! November 5, 2018
Reviewer: Carl Miles from Braxton, MS  
I couldn't be happier with my purchase from Fortress. Mike was quick to reply to my texts with helpful answers. The order shipped fast and free. Paid no taxes since I live out of state from Fortress. The price was unbeatable from anyone else. These uppers are the tits. If you’re on the fence about getting one, don't wait any longer because they're worth every penny. 10/10 - would do business with Mike again!

Great product and excellent customer service October 1, 2018
Reviewer: Pasit from Portland, OR  
My upper arrived in 3 days from date ordered. Can't beat that. Fit and finish was excellent - on par with my LMT rifle I would say for less money. The piston system is very interesting and upper worked great with wolf ammo.  Very content with product and help from Mike.

Great and Fast Service August 7, 2018
Reviewer: Paul Betz from Spokane Valley, WA  
This was my first order with Fortress Tactical, but it won't be my last. My upper was shipped out in less than 24 hours after placing my order, and I received it within 2 days after shipping. The price on the upper couldn't be beat anywhere else. Mike will definitely be getting more of my business in the near future.
