M14 Flash Hider

The United Defense M14 Flash Hider is a MIL-spec replacement flash suppressor with an integrated bayonet lug, designed for M14 and M1A pattern rifles. Forged from steel and finished in a deep blued coating, it matches the harmonics and silhouette of the original GI-issue flash hider, preserving accuracy while restoring the rifle's authentic military profile. The four-slot ported body cuts visible muzzle flash and accepts standard M14 bayonets. A solid pick for M1A owners looking to bring their rifle back to GI configuration or replace a worn factory unit.

    Slapped this on my Springfield M1A and it fit like a glove, no fitting required. Looks correct and functions great. Put about 200 rds through it last weekend and flash suppresion is noticably better than the bare muzzle. Bayonet lug indexes perfectly with my M6 bayonet too which was the whole reason I bought it.

    Drop-in fit, no gunsmithing needed,Bayonet lug works perfectly

    Been running M1As for close to 20 years and ive tried a few different muzzle devices over the years. This one fits perfect, no timing issues, and the bayone lug is actually usable unlike some cheap ones ive seen. Threw about 300 rounds of surplus through it at the range last weekend and zero issues. If your running a M1A or M14 build this is the one to get, dont mess around with the cheap stuff.

    Solid fit and finish, Bayonet lug actually lines up correctly

    This flash hider matches my original M14 perfectly no weird shine or wrong angles. The bayonet lug works great with my M6, and the blued finish blends in with the rest of the gun.

    Military-spec

    I bought a Springfield M1A a few years ago and it always bugged me that it didnt have the proper flash hider and bayonet lug like the original military M14. This fixed that problem immediately. The install was straightforward and once it was on there my rifle went from looking like a commercial sporter to looking like a proper M14. The blued steel finish matches my barrel really well and the machining quality is excellent with clean threads and no burrs. I also mounted my M6 bayonet on the lug and it locked in perfectly which was the moment I knew this was legit mil-spec and not just some aftermarket approximation. First thing everyone says when they see my rifle now is that it looks like the real deal.

    Worth every penny of the 35 bucks.
