Skeletonized aluminum jig lets you observe the function of the sear, hammer, and disconnector engagement points while under normal spring tension.

I like being able to adjust the set screws to set the engagement and resistance. A time saver compared with installing and removing to fine tune.

Excellent tool

Should have bought this much sooner. Excellent tool for fitting and testing ar platform triggers.

Great product & tool

Found this to be very helpful for performing and testing trigger work. Allows you to see how the parts are actually functioning. Also found it good to practice trigger pull.

Best trigger fitting jig!

I purchased this jig for test fitting Mil-Spec triggers prior to installing them in lowers. It allows perfect viewing of the hammer and trigger mating surfaces and lets you see how they are contacting each other. Checks for hammer cam over which adds pounds to the pull. After checking in the jig, using a Power Custom Series II stoning fixture lets you make the correct adjustments necessary for a ZERO creep, glass break trigger and additionally you can lighten the pull by setting the correct angles. Saves MANY repeated fittings into a lower receiver and ultimately wear and tear on the pin holes. Using a left over A2 grip on the jig gives you an actual feel of how it will be when installed. Mounting in a vise will also work.

S.I. Trigger jig.

This is a great idea, but one small issue was experienced. The trigger and hammer pins provided should have threads to keep them in place. Other than that, worked very well.

Time saver

Makes setting trigger pull for a build so much easier. Great little gadget, should have gotten one ages ago.
