M-16 Disconnector
The M-16 Disconnector is a full-auto fire control group component that controls the firing cycle between semi-automatic and full-auto modes on the M-16 platform. Machined from hardened steel to MIL-SPEC dimensions, it features the extended tail required to engage the auto sear assembly — the key difference between an M-16 disconnector and a standard AR-15 part. It drops into the standard fire control pocket and works with the factory disconnector spring and pin. Intended as a service or repair part for armorers and owners of legally registered full-auto M-16 rifles.

Description
Features
- Full-Auto M-16 Fire Control Component — Core part of the M-16 fire control group that works in conjunction with the auto sear to regulate single and full-auto fire.
- Extended Tail Design — Longer rear leg engages the auto sear assembly, distinguishing it from the shorter AR-15 semi-auto disconnector.
- MIL-SPEC Construction — Manufactured to military specification dimensions and tolerances for reliable lockup and consistent hammer release.
- Hardened Steel Build — Heat-treated steel resists wear from repeated hammer hook engagement under sustained fire.
- Drop-In Replacement — Direct fit into the standard M-16 lower receiver fire control pocket using factory pin and disconnector spring.
- Registered Auto Weapon Use — Intended as a service or repair part for legally registered full-auto M-16 platforms and select-fire variants.
- Compatible Spring Channel — Stepped underside accepts the standard disconnector spring for proper trigger reset tension.
- Precision Machined Hook — Cleanly cut engagement surface delivers a crisp, predictable disconnect for safe single-shot firing.

Does exactly what it's supposed toDropped this in my lower and it fit perfect first try, no fitting needed. Mil-spec all the way, feels solid and well made compared to some cheaper ones ive bought before. Reset is crisp and trigger pull feels clean.

Fits perfectThis disconnector dropped right into my lower with zero fuss, engagement surface looks properly hardened just like it should be. I was a little nervous ordering a fire control group part online but this thing is SOLID, no slop, no weird fit issues at all.

Exactly what my lower neededDropped this in my DPMS lower alongside a new trigger group and everything reset clean right out of the box. Put about 400 rounds of M193 through it at the range last weekend with zero issues. Ive swapped a lot of FCG parts over the years and this one feels like quality mil-spec stuff, no slop, no weird geometry. Shipping was fast too, had it in 3 days which I wasnt expecting.
Solid mil-spec fit and finish

Great qualityThese are the real deal and the machining is top notch. I have been using it for a few range sessions now and it has been working flawlessly. It is nice to have something that feels like real military parts.

Reliable M16 disconnector, no complaintsThis disconnector is fine, fits like it should and the engagement surface looks properly staked and hardened. I called customer service before ordering to ask about compatibility with my Aero lower and the guy on the phone actually knew what he was talking about which is rare anymore. Would buy again.
