SIG MCX Barrel Supporter Valken trigger units from common manufacturersImproved upon the original designed for a tighter tolerance and more stable barrel setup. The MCX barrel supporter holds the outer barrel firmly in place preventing wobble, rattling, and inconsistency between shots. The additional support screws and reinforiced aluminum build allow for more muzzle devices such as suppressors and tracer units to be held securely without compromises your barrel's positioning.
