Lengthen your barrel

Pin & Weld Service
$60 - 90

Need a muzzle device pin and welded to your barrel shorter than 16 inches? We offer an in-house pin and weld service to make that happen along with other welding services based off your request. 

Pin and Welding - Barrel Length Requirement

Is your rifle barrel is less than sixteen inches long in length, by ATF/NFA requirements, having it installed on any rifle would create a short barrel rifle. (Except when properly installed per ATF/NFA requirements, on an AR Pistol.) 

One method mentioned to meet this requirement is to pin and well your muzzle device on your barrel so that it is permanently attached, thus extended the actual length of the barrel by adding the length of the muzzle device.

"Permanent methods of attachment include full-fusion gas or electric steel-seam welding, high-temperature (1100°F) silver soldering, or blind pinning with the pin head welded over."

- ATF E-Publication 5320.8 Revised: April 2009

Be aware that all muzzle devices are different in length and the correct length when combined with the barrel, must be equal or greater than sixteen inches.
