[SHOT 2018] SIG MCX 300 Blackout Integrally Suppressed Upper
This review of the SIG MCX 300 Blackout Integrally Suppressed Upper from SHOT Show 2018 highlights its modular handguard system, which is zeroable for accessories. The upper features a 6.75-inch barrel with a pinned and welded 19-baffle titanium suppressor, making it a 'one-stamp' NFA item. The modularity also allows for a barrel swap to 5.56 NATO.
