The Diablo Upper is Primary Weapons Systems’ answer to the 7” ...more__ AR-15/M-16 series upper. Rather than simply bolting on an existing product and calling it revolutionary, PWS stepped back and designed a system from the ground up to work specifically with the extreme pressures of the 7” barrels.
The Diablo upper utilizes a long stroke piston system for additional dwell time and smooth recoil. The system is rounded out with the new CQB comp from PWS - a comp designed for short barrels that compensates, suppresses flash and directs all the blast forward.
This product replicates: MIL-STD- Type III Hard Coat Anodize USSOCOM Flat Dark Earth.
Which, I believe Madbull did a great job replicating. Madbull extra effort pays off; in the long run.
I'd like to thank: Airsoft GI Staff for the excellent services.
GREAT BUNCH OF GUYS.
JOSH for special ordering this product.
Best airsoft experience :)
Newly approved USSOCOM F.D.E Type 3 Anodizing.
Must use Vltor upper receiver.
Won't work with standard flattop receiver. Looks odd.
Have to mod Magpul XTM covers to fit.
Would not recommend to novice builders.
