has anyone come up with a simple mod to improve the trigger on a bushmaster m17s bullpup? it's a great handy little poodle shooter but the trigger pull could definitely use some improvement.

Kampilan, you might try one of the drop-in triggers. They aren't cheap but they are pretty easy to install. George

I don't know of anyone publicizing their work on the Bullpup, but I understand your desires! Watch out that that hammer spring legs don't drop below the sear. It will render the fire control system inoperable, and it can happen when just cleaning the rifle. I'm not impressed with this, but it's a fun little rifle.

I have two suggestions. Buy a tube of Moly-Slide (from NECO Enterprises, and available from Brownell's, Natchez, etc.). It's a high-grade, concentrated Molybdenum Disulfide grease.

First, apply a little of this to the bearing surfaces. Then, coat your thumb and index finger and apply a little moly to the entire trigger bar (that run from front to rear). You won't think this is a match trigger, but it will substantially improve the quality of the trigger.

If you learn better ideas, let me know!

I used to work for Bushmaster, and now that I don't represent the company anymore, I can throw out some hints.

First, yank the spring out of the middle of the trigger. It really doesn't need to be there at all and only increases the trigger pull. This is the spring between the trigger and the cam in the middle of the trigger. Removing that will help a lot.

Lubing all contact surfaces will also help, especially where the trigger cam rides on the inside of the frame, lots of friction right there.

If you're really handy, you might want to make another trigger cam out of aluminum or something, change the location of the holes slightly, and try that. You can change the leverage that way and change the trigger pull a lot.

Because of the linkage, smoothing the contact surfaces in the firing pocket usually doesn't really accomplish much, and I always recommend leaving them alone. You can do a lot more just by smoothing the link rod itself and lubricating it well.

That's pretty much it without getting too crazy and making custom springs and stuff like that. These fairly simple mods will improve the stock trigger a lot, but it will still be heavier than a regular trigger. Bullpup triggers are tough to tinker up, it's the design that complicates matters. Anyway, hope this helps.

With my shield or on it...
