    Proper Mil-Spec Hammer, Finally Got One Right

    Ive been chasing down correct mil-spec M16 fire control parts for my registered receiver build and this hammer is spot on. The hook engagement surface where it catches the auto sear is properly ground and the geometry is correct... not like some of the aftermarket stuff floating around on GunBroker that's cast and out of spec. Hardened steel, parkerized finish looks correct, and the sear engagement is crisp with no slop. Compared to the Luth-AR M16 hammer (which comes with the J spring included), this one doesn't ship with a spring but honestly I already had spares so that wasn't an issue for me. Installed it alongside the correct disconnector and auto sear in my registered M16 lower and it runs like a sewing machine. Don't cheap out on surplus hammers from SARCO that have wear on the sear hooks get a new manufacture one like this.

    Correct mil-spec dimensions and geometry Properly hardened steel with clean parkerized finish Sear hook engagement is precise out of the box

    Doesn't include J spring like some competitors

    I've installed this M-16 hammer in my rifle and it's been a game changer. The quality is top notch, and it's been reliable so far. I've put a few hundred rounds through it without any issues

    The customer service was also great, they responded to my email right away when I had a question about compatibility

    I work on NFA firearms professionally and keeping correct spec replacement parts on hand is essential for my shop. This M16 hammer is exactly what it should be with proper hook geometry and the correct engagement angles needed to function safely and reliably with the auto sear and disconnector. I have installed this same hammer in two different registered builds now and both ran flawlessly with zero timing issues. The heat treatment feels correct based on the hardness and the pin hole is sized perfectly with no slop on the trigger pin. For armorers and SOTs who need reliable mil-spec full auto components this is a solid source.

    Correct hook geometry and engagement angles for safe and reliable full auto function
    Heat treatment and pin hole tolerances are properly spec which ensures consistent performance

    Would be great if they offered a bundle on all the parts

    This M-16 hammer is exactly what armorer-level maintainers need to keep registered rifles running. The mil-spec construction is obviously top-quality and the new condition is perfect. Having spare parts like this means you can keep your rifle functioning reliably for years. Already have it as a backup and it gives me peace of mind for long-term operation.

    New condition and military contract production style provides reliability always
