Sig Sauer MCX Build 7.62x39mm 30rd, FDE
1 in stock
Description
This Pre-Owned Sig Sauer MCX Build is a semi-automatic 7.62x39mm AR-pattern pistol assembled around a SIG MCX upper with an 11.5 inch barrel. The MCX line uses a short-stroke gas piston operating system rather than direct impingement, and SIG's 7.62x39 upper kits were designed to run on standard AR-15 pattern lowers, which is what makes a build like this one possible. Shooters who want the ballistics of 7.62x39 in a short, familiar AR-style package are the natural audience here.
The configuration is dressed out in FDE, with an FDE M-LOK handguard and FDE pistol grip paired to the MCX upper assembly. It comes equipped with a pistol brace and ships with one magazine. The firearm shows normal handling wear consistent with prior use and functions as intended.
Sig Sauer MCX Build Features
- Short-stroke gas piston operating system that keeps combustion gases out of the receiver and runs cleaner across shorter barrel lengths
- SIG MCX-pattern upper chambered in 7.62x39mm, giving heavier bullet weights and short-range terminal performance from an AR-style platform
- 11.5 inch barrel that keeps the overall package compact for vehicle storage, truck guns, and tight-quarters practice
- FDE M-LOK handguard with open attachment slots along its length for lights, hand stops, and sling mounts
- FDE pistol grip and black pistol brace that round out the furniture and support one-handed and braced shooting positions
- AR-pattern lower receiver layout with controls and ergonomics most shooters already know
