Description
Razor · SKU PW · Pin & weld service · $69.95
Pin and weld. Make the short barrel a 16? rifle.
Add this SKU to a barrel order when a muzzle device has to be permanently attached so overall barrel length makes 16?. PAMAX pins and welds the device to the tube. Two ways to run it: use one of our muzzle devices, or ship us yours with the order number on the package.
This is a service, not a barrel
Order PW with the Razor barrel and the muzzle device you want attached. A 14.5?, 13.9?, or 13.7? barrel stays an NFA short barrel until the welded device brings measured barrel length to 16?. We do not pin and weld a device onto a barrel we did not sell unless that is arranged before the order ships.
How to order
Option 1 — our device, our barrel
Add this service, the Razor barrel, and a PAMAX or stocked muzzle device to the same cart. We pin and weld that device to that barrel before it ships.
Option 2 — your device, our barrel
Add this service and the Razor barrel. Ship the muzzle device to us with the order number marked on the package. We weld your device to our barrel.
Fitment is on the customer
Thread pitch, bore diameter, and material have to match the barrel before the device leaves your shop. Wrong thread, oversize bore, or the wrong alloy will not be welded. Ask before you buy if the combo is not on the cheat sheet below.
We can source the device
If you need a mount we do not list, reach out before checkout. We can often buy the muzzle device at a better price and weld it here instead of running a second shipment.
Length cheat sheet
These pairings are the combinations we weld to make a legal 16? rifle-length barrel. Do not assume a different brake, flash hider, or suppressor mount makes the same length.
| Barrel | Muzzle device | Result |
|---|---|---|
| 14.5? Razor | HADES Hybrid | Makes 16? |
| 13.9? Razor | Dead Air Keymo | Makes 16? |
| 13.7? Razor | Dead Air Keymo | Makes 16? |
| Any other length | Confirm before order | Do not assume 16? |

Do not ship a mismatch
Devices sent in must be the correct material for a permanent attach. Confirm thread, bore, and alloy against the barrel SKU before the box leaves.
Pin-and-weld is semi-permanent. Plan the muzzle device before we strike the weld. HADES is sized for 14.5?. Dead Air Keymo is sized for 13.7? and 13.9?. Anything else needs a message before checkout.
