Sig Sauer MCX .300 Blackout Barrel Cutting Service
Due to popularity, we have added a set amount of inventory for this service to avoid going over capacity. Please read the terms and conditions page about barrel lead times and understand them completely before purchasing this service.
PMM is now offering a comprehensive Barrel cutting service for the Sig Sauer MCX .300 Blackout. (DOES NOT APPLY TO VIRTUS)
Each barrel is meticulously cut, re-threaded and crowned off the bore centerline. 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 has discovered during their testing that there is the potential for factory piston dimension discrepancies which may prevent your rifle from properly cycling subsonic ammunition. To fix this, PMM has machined a titanium piston that is lighter and held to higher tolerances. We will contact you if we determine that it is necessary to purchase the PMM titanium piston in order for your gun to cycle after reducing the length of your barrel.
Due to the lack of a sufficient shoulder with factory .300 Blackout barrels, PMM machines a custom shoulder ring to be used with muzzle devices and suppressors.
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.
Option#1, Cut Re-work Handguard: Handguard is Re-coated on the cut section with a 2 part Bake on Epoxy Black paint +$ 75.00
