    No joke turn around time

    Posted by Nathaniel Cook on Jun 4th 2024

    Sent in my 14.5 p/w 516 to be cut to 11.5, shipped the upper Wednesday and by Friday afternoon I got an email saying they were shipping it back to me, I looked at the UPS tracking and saw it got to their shop at around 11am and by 2pm a shipping label was created to ship it back. At first I thought maybe something was wrong until it came back threaded crowned and cut to 11.5 inches and beautifully done. I honestly can not believe the turn around time and the only explanation I can come up with is that either ZRTS is run by cyborgs with lathes for hands or every other gunsmith I've done business with is a lazy bastard.

    High quality machining

    Sent in my 14.5” 516 upper to be cut down to 11.3”. The turnaround time was extremely fast and the quality of the work is second to none. Gun cycles perfectly with and without a can. Use ZRT’s gunsmith services with confidence that you’re getting the very best in the business. A++

    516 barrel cut

    Posted by Sean Buyce on Dec 10th 2023

    This is the second time that I had work done by these guys. I don’t know what kind of voodoo wizardry that they’re doing over there but they are amazing. Within an hour of them receiving my barrel I got a shipping notification that it was on the way back. They cut my barrel to 10.3 and did the gas ports. It was received on a Monday and back in my lap Thursday morning. Solid work and they even gave me the Black Friday discount even though I forgot to add the code. I highly recommend them. They do great work and calling them fast is an understatement. Thanks again

    Turn around time was amazing!

    Sent the upper with UPS on August 2. It was delivered to my door on August 4! Looks good and I will leave a performance review after it gets tested with and without a suppressor.

    Awesome service

    Posted by Ian on Jun 16th 2023

    They do not kid around when they say “fast turnaround”. I shipped my upper, they did the requested work, and it was delivered to me again all within the same week. The threading looks professional, and they answered my emails either same day or the next business day. I’m more than happy to ship all my future cut and threading jobs from VA to them.

    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 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.
