Sig Sauer MCX .223/5.56 & .300 Blackout Pinning and Welding Service
PMM will take your MCX barrel and precisely cut, crown, thread and then finally pin and weld on the Muzzle Break or Flash Hider of your choice to meet the BATF requirement of 16" minimum barrel length. If you have selected a Custom crown, please include your specifications in the Notes Section during Checkout. You will need to ship your muzzle device to PMM unless you are also purchasing one from us.
We test and function check each barrel on both the Non suppressed and Suppressed setting (Surefire and Gemtech Suppressors) to make sure the rifle locks back on the last round for both settings. You can also send your suppressor to PMM so that we can use it during testing and function checks.
PMM also offers the PMM handgaurd cut and re-work option for the desired length of barrel for your MCX, This service is available in two finish options in the drop down list.
