I have performed a few trigger mods to my 15-22 and thought I would share the results.

Let me start by saying, I bought the rifle new, it is a MOE model. The trigger pulls referred to are using a Lyman digital trigger pull gauge and using an average of 5 pulls per measure listed, same spot on trigger and same angle pulls each time. Each test session with the upper tipped off, thumb in front of, not touching the hammer, hammer into my thumb when sear releases.

The rifle has now had approx 1500 rounds through it. 1 fail to feed at approx 100ish rounds 1 ftf at approx 200 rounds. Both attributed to break in/carbon build up. No further feed/eject malfunctions.

Now to the trigger. I measured the trigger pull (TP) after the initial cleaning and before the first range session with slight amount of gun oil to sear, TP 7 lb.

After approx 500 rounds, disassemled trigger mechanism, thorough cleaning, slight amount of gun oil applied to sear, TP 6lb.

Then disassembled, applied polish compound to sear, dry fired in same manner of the TP testing approx 20 times/pulls. Disassembled and thoroughly cleaned mechanism. After polish with slight amount of gun oil to sear, TP 6lb 13oz.

Then cleaned oil from sear and applied a small amout of Bel Ray assembly lube with moly to the sear, TP 6lb.

Then shot approx 300 more rounds and tested after thorough cleaning and reapply Bel Ray lube, TP 5lb 12oz.

Installed JP yellow 3.5 springs using Bel Ray lube, TP 4lb 8 oz.

Shot approx 700 more rounds, thoroughly cleaned, reapplied Bel Ray lube, TP 4lb 8oz.

My conclusions are, you can get approx the same effect from either applying polish to sear and dry fire or just use the weapon for a while and you get the same reault. Doing both doesn't seem to help, in fact, if you look at the before and after TP readings, it seemed to be the opposite. I didn't notice a difference between the feel of the trigger/smoothness after polishing or use of the weapon. The two major changes occurred with the Bel Ray lube with moly and the JP springs.

Keep in mind, the testing was not done under "lab conditions", but in real world use.

Hope this info is helpful.
