MPX Barrel / Handguard Service (+ Two Way Insured Shipping)
ZR Tactical Solutions
These guys are awesome. I had my 516 barrel cut from 14.5 to 11.5 and the accuracy is astonishing with just 55gr ammo. I wouldn’t hesitate to recommend these guys to anyone.
Absolutely stellar service!! My barrel was cut, gas port regulated and shipped back to me the EXACT same day they received it. They've earned my respect and future business.
ZR did a cut and thread for my Sig 516, same day they got it, it shipped out the same day. Shoots like a dream. Thanks!!!
ZR Cut and threaded my 14.5" 516 to 10.5". They also did the gas system work. I'm very happy with the upper, and it is gassed perfectly with and without the silencer. Highly recommended.
