Well I finally got to shoot my new PC 15-22 last night. I don't know whether to be happy or dis-appointed.

I took the time to compare it to my MOE with different ammo. and all I can say is that either I got an outstanding MOE or a so-so PC. The MOE grouped just as tight as the PC(this at 50' indoors). The only difference was POI but the groups were almost identical. Also, the PC has a 2 stage trigger, and it is pretty smooth out of the box and I haven't done anything but clean and re-lubed it. It seems to have a fairly heavy pull to it but it breaks cleanly and consistently and I expect that all to just get better as the gun settles in.

Strange thing though, I currently like my trigger on the MOE better than the PC. After all the discussion about the different mods. that can be done to the stock trigger, I think it is very nice and was easy to work with. That dangerous set-screw mod. hasn't caused any irregularities so far, and as I stated before, I will be the first one to quit using it if the gun mis-behaves. I will post here immediately if a problem arises.

I have no plans at this moment to tinker with the PC FCG until it's had plenty of break-in time. It, unlike the MOE, was never gritty feeling and the take up is consistent. Since it is a 2 stage trigger, I won't be using the set-screw mod. as I noticed that what-ever I read, it always said "single stage trigger mod."

BTW, so far all of my 15-22's have been trouble free on all fronts. Just an occasional FTfire(rotated cartridge, boom)a FTfeed,(didn't load the mag just right) and no FTejects. Knock on wood, they'll all fall apart the next time I'm out.

I'll have pics later this afternoon of the different groups.

Pics of the different ammo groups will be posted here later today.

Results from shooting on sandbags at 50 yards with match ammo would be good to see.

I personally never understood the draw of a two-stage trigger pull. Give me a single stage with little to no creep and a pull weight under 6lbs and I'll be happy.

My MOE showed up with a heavy but crisp trigger at 8 or so pounds, and after dropping in the JP light springs I have a much lighter pull but it has noticeable creep as the sear/hammer faces slip from the lighter tension. I don't know which is worse. I haven't gotten in to do any polishing or cleanup since I changed springs, however.

I'd also be curious if you could get some match ammo and open the range out to 50 or 100 yards. At 50ft I would think you won't be seeing more than ammo variation and should be able to keep "groups" under an inch.

I would have to go with 50' not being an adequate test between two rifles. I finally dialed in my MOE BUIS yesterday (two 25 yards), and once done, at 15 yards 5 shots at a time were most times within an inch - several times almost making one hole. At 25 yards it was a different story, partly because at that distance the front sight over-covered the small target. at 25 yards it was typically more like 3 inch groups with distinct single holes, and an occasional flyer that would be 5-6 inches off target (biological misfire). This was at an indoor range, usually in a standing position unsupported and firing at about 1-2 second intervals five at a time.

Extra Mags - great investment! Load em all up at home and make the range time far more efficient.

Monday I should be receiving my PA3 multi and 3x magnifier... looking forward to that! The guys there were very helpful helping me get sorted out.

Some like the two stage and some don't. Physically, its mostly to do with predictable tactile feedback at the trigger finger when firing.

The single stage trigger releases the hammer after a steady squeeze is applied and needs a steadily increasing pressure (through the whole pull to firing) to overcome sear/spring/mechanical resistance. This requires the shooter to "walk" through the trigger pull and find the "release point" with a steadily increasing pressure. During that "steadily increasing pressure" there is some inaccuracy introduced because as you increase pressure through the pull you place more pressure on the trigger and, physically more tension on the trigger finger for a longer amount of time, the more pressure you apply the longer its applied thru the pull the more likely you are to slighty move the weapon some over the time period of the "steadily increasing pressure" to release point.

Its different with the two stage because the firing release point is reached and thats it, you don't pull through the entire trigger pull with a "steadily increasing pressure", its the same each time - so you get more of a "squeeze-bang" rather than a "squeeze-pressure increase over time-wait for it-bang".

In a two-stage trigger, the hammer is released after two distinct amounts of spring/mechanical resistance are overcome. The initial stage of resistance feels "lighter" and is relatively long at (approximately/generally/can vary) 1/8 of an inch. The second stage of resistance is greater than the first stage resistance but very short in duration thus no constantly increasing pressure through the entire trigger pull. The result is a predictable, consistent, "crisp" trigger pull and there is no "walking" through the squeeze with that "steadily increasing pressure". Two stage triggers are great for semi-auto weapons for that reason with rapid fire generally being more accurate with a two stage.

There in lies the attraction for two stage triggers, kinda basically.

(Ok, I think I said all this right. At least I know what I mean and thats the important part because my targets shoot back )

I'd like to see some pics of the groups at 50 or 100 yards with match ammo, and maybe benched or sandbaged groups with it.

I kind of wondered if the POI might expand at range. 50' is'nt much to deal with. I can't wait to go stretch the legs on these lil' guns.
Film at 11 tomorrow....
