Which Trigger Is Right for You?

Four trigger types, explained in plain English – so you can pick the right one the first time.

Fires on pull & release

Reflex Triggers

One shot when you pull and a second when you release. Drop-in designs with a hold-to-cancel option for the second shot.

Available for: Glock (G-Flex), AK (AK Flex) and KRISS Vector (K-Flex)

Bolt-driven reset

Assisted-Reset Triggers

Uses the bolt carrier’s energy to push the trigger forward to reset, with the same crisp 4.5 lb pull in every mode. Requires a full-auto profile (M16) BCG.

Available for: AR-15 (Flex3MR)

Selectable mode

Binary Triggers

A selector lets you switch between standard semi-auto and pull-and-release mode, so you decide when the second shot is active.

Available for: AR-15 and AK platforms

One shot per pull

Standard & Drop-In Upgrades

Mil-spec replacements plus flat-face and two-stage drop-in triggers for a cleaner, lighter break on a standard semi-auto build.

Flex3MR Assisted Reset Trigger for AR15 – AMBI

Price:

$229.99

Flex3MR Assisted Reset Trigger for AR-15

The Flex3MR uses the bolt carrier’s energy to drive the trigger forward to reset, so every follow-up shot starts from the same crisp 4.5 lb break. The included ambidextrous selector switches between Safe, Semi and Flex, and the pull weight stays the same in both firing modes.

  • Drop-in cassette for mil-spec small-pin (.154″) lowers
  • Requires a full-auto profile bolt carrier group
  • CNC-machined 7075-T6 housing with hardened steel internals

AK Flex Pull-and-Release Trigger

The AK Flex installs in AK47, AKM, Draco and most AK-pattern rifles and pistols with your standard trigger pins. There’s no milling and no permanent modification. A 3-position selector gives you Safe, Semi and Pull-and-Release, where the rifle fires once on the pull and once on the release.

  • Fits 7.62×39, 5.45×39 and 9mm AK builds, including PSA, Arsenal, K-USA and Zastava
  • Single-stage break with minimal take-up
  • Pull-and-release triggers are restricted in some states, so confirm legality before ordering

Is an M16 BCG Legal in an AR-15?

Yes. 100% legal — m16 bcg legal is a fact. Under federal law and ATF rulings, an M16 BCG is NOT a machine gun part. You can legally put an M16 full-auto profile Bolt Carrier Group in your semi-auto AR-15. Millions of Americans do it every day. It’s MIL-SPEC. The confusion comes from the name […]

Why Is My AR15 Over-Gassed? How an M16 BCG Fixes It

If you’re asking why is my ar15 over gassed — brass flying to 1 o’clock, violent bolt speed, and gas to the face — you are over-gassed. 90% of factory AR-15s are. Why? Manufacturers open the gas port wide to make sure the gun runs with cheap .223 steel-case ammo. Add a carbine gas system […]

Do You Need an M16 BCG for Fostech Echo?

Yes — M16 BCG for Fostech Echo is mandatory, not optional. Fostech’s official install sheet for the Echo Sport, Echo 2, and Echo AK says “M16 Full-Auto profile BCG required.” If you try to run a lightweight AR-15 semi BCG or a skeletonized carrier, your trigger will not reset on release. Why does a binary trigger need […]
