Pin/Weld Muzzle Device


SKU: N/A Categories/Brands: ,


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.

If you send a barrel and muzzle device to be pinned and welded, we pin and weld it. If the combo you send doesn’t make 16″ OAL, that’s on you. Make sure what you send is long enough if 16″ OAL is your goal.

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

We do not install accu-washers. If you want to use them, you must install the shim you want used.

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.


If you don’t submit your order, the work will NOT get done. Do NOT send anything without submitting an order online first.

When sending your order, please include:

  • A list of what is in the box.
  • Your name/order number on the OUTSIDE of the box.
  • Enter as much info about what you want done as possible in the comment section at checkout.
  • Print the confirmation page and sign the CC authorization statement.

Please read through the FAQs before calling with a question or placing your order.
