In Lead We Trust Replacement Barrel Sig Sauer MCX, 16"


Default Title
Gen-2 MPX-type replacement Drop-in Barrel & Gas Block assembly:

Barrel with a replacement pre-installed gas-block, for even easier end-user installation. Proven 4140 hard-melonite barrel, pre-installed/pinned in an Ordnance steel hardened gas-block. All gas-block dimensions are machined within 0.0005", to correct specification, and hardened.

This option allows easy barrel-assembly swaps for end-users who choose not to remove the barrel from the gas block, during the process. 
All that is required, is removing the factory tappet and gas valve and installing it in your new ILWT bbl/gas-block assembly. 

Pre-installed Barrels are available in 14.5", and 16.25" lengths, with 1/2-28 concentric threads. Thread protector is included.
