CTM CNC 7075 Aluminium Trigger Bar for AAP-01/C

The bar is what carries your finger’s movement back to the sear, and the factory one is a pressed part doing a job that wants rigidity. Replacing it with a single piece of machined 7075 takes 3.2 g out of the linkage and removes the flex that makes a long pull feel vague.

It is a 2.0 g part, which sounds trivial until you remember it is moving every time you fire. Paired with one of the lightweight triggers in this range, the whole front half of the mechanism gets lighter and more direct at once.

CTM note that 7075 sometimes finishes with a mark or a slightly flat patch. That is the alloy rather than the machining, and none of it shows once the bar is inside the frame.

Specifications

Good to know before you buy

This part lives inside the frame, so fitting it means stripping the lower. Allow yourself an evening and somewhere to put the small bits rather than doing it before a game.

It is a linkage change, not a spring change. If your pull is heavy rather than mushy, this is not the part that fixes it.

Expect the alloy to look less glossy than a 6061 part. CTM flag it up front and it is cosmetic.

Frequently asked questions

What does it actually improve?
Directness. A rigid machined bar flexes less than a pressed one, so the movement at your finger reaches the sear without being absorbed on the way.

How much lighter is it?
3.2 g lighter than the part it replaces, at 2.0 g all in.

Is it hard to fit?
It is inside the frame, so the lower has to come apart. Straightforward if you have stripped an AAP before, fiddly if you have not.

Why does it look slightly dull?
That is 7075 behaving like 7075. CTM mention it themselves and it has no bearing on how the part works.

Do the finishes cost different amounts?
No, all seven are the same price.
