Attach a muzzle device permanently to bring the OAL to 16, or AWB Compliance. This is the pinning service only. This price does NOT include threading or the muzzle device. There are different rates for different devices so be sure to select the correct device below whether you are sending the device or buying from us.

Be sure to send your barrel nut if sending a barrel with a gas block.

We will NOT pin any device using a 13” URX 4 and a 13.9” barrel.

We do NOT pin any type of brake through any external threads(OPS/AE). We do NOT perm any titanium or aluminum muzzle devices.  We try to stock some of the more common options here.

If this is the only service on your order, turn around is 2-3 business days.

    This service is amazaing! Received it back in much less than a week. If you need/want a pinned muzzle device in a hurry that is also quality work, Order Here.

    5 stars isn’t enough for these guys. Had a factory BCM upper disassembled (which is an absolute pain), barrel chopped to 14.5″, suppressor muzzle device pinned and welded, and was all done and back at my doorstep in 6 days. Could not be happier with the work, service, and turnaround time. Would definitely recommend ADCO and will be using them again in the future.

    As the others reviews say, this service was definitely by far the best pin/weld I’ve seen to date. Very crisp and clean. No bulgy mess, very well executed! Same as the others, turn around time was extremely fast. Upper was sent out Tuesday, arrived Wednesday, that same Wednesday I was notified of a return shipment, and received it at my door step by the weekend.

    If anyone needs a permanent muzzle device done, this is it!

    Incredible job as always. Turnaround was astonishingly fast. The day they received the barrel they did the work. The NEXT DAY I had my barrel. Lifetime customer here.

    Incredible work, I could no be happier. Overnighted the upper on Monday back in my hands Thursday (WOW). The timing of the brake is perfect and the weld is a thing of beauty. Adco will definitely get my work from now on 10 out of 10 !!!

    I just got my upper back and the muzzle brake was installed correctly and the weld is clean and unobtrusive. Excellent work, and the turnaround was lightning fast. They got it on Friday and shipped it back to me…on Friday!

    The brake was pinned and welded beyond my expectations, it’s as clean and unnoticeable as is possible! The turnaround is incredibly fast as well. I shipped this out on Monday and had it back the following Saturday, Five days! Awesome folks, will definitely get work done by them again!

    Had a SOLGW Nox flash hider pinned and welded to a Ballistic advantage 13.7. If you want a pin and weld, send your barrel to these guys. Idk if I got lucky or something, but once my barrel and everything with it arrived at their store, it took them only about an hour or two to get it back to UPS and on its way back to me. When I saw I got a new tracking number that fast, I seriously thought that I messed up or something and they had to send it back to me, but nope, everything was fine and they had already finished the work. Also I asked them to time the flash hider a certain way and they did so as perfect as humanly possible. Really couldn’t ask for a better experience.

    This is the second time I have used these folks for gunsmithing, and I am very happy I found them. Same-day turnaround, reasonable price, and actual shipping charges. The pinning and welding was clean and smooth. You can’t beat it!

    Highly recommended. Turnaround was something like two hours or less between the time it was reported delivered to when I had a return tracking number from Adco. The weld is very clean, hardly noticeable. Could not ask for better service or work quality.
