700 rounds through mine so far. No jams.

I don't know if I can replace the M&P-22 for SC, since its so stupid light. But the NC-22 is maybe a half pound lighter then my JP upper, so It should make it a great practice tool when working on stances, also will probably shoot some sportsman team challenge with this thing, now that I have everything I need.

Do you guys know, if NC works with Jard trigger ? Is that a high quality item, have you tested accuracy ?

[DocMedic]

Well I don't know about Jard, but it does work with my high dollar Golds Trigger which is basically set at 1.5lbs at two-stage.

As for accuracy, I don't know yet, I wasn't to impress with it zeroing at 25yards, but it is a stainless steel barrel so it needs proper brake in, I'll report back when I got about 500+ rounds with it and some proper barrel braking in time.

Quality wise, Real nice the one i picked up was there 20" bull barrel version. Upper itself ways 4.75+ pounds approx, I actually got tired lifting it after about 10mins of Offhand drills.

Hoser what version did you get and hows the accuracy so far since you already have double the round count on it then I?

I got the 18 inch. I am going to test for accuracy Friday night with several different flavors of ammo.

For practice I am just going to run with Federal Bulk Pack.

I have tried it with four different triggers. Geissele, AR Gold, JP and GI. Runs like shit through a goose. I have a JARD in a lower somewhere, I will test it later.

I *do* know that with a can on, most timers still cant record the shots...

Nice! I been thinking about one of those just to cut down on the cost to fire .223. What that set you back if you don't mind me asking?

What does "NC" stand for? Does it use a ceiner type bolt?
I have approx. 35,000 rds thru my "Model 1" dedicated 22 upper.The ceiner bolt does not like notched hammers. Approx. every 3,000 rds. the Rock River match hammer would break, including one JP match hammer which broke in half. I use a mill-spec hammer now. I've broken 2 firing pins so far. Spikes Tactical uses beefer firing pins. Around the 35,000 rd. mark it started to double on me. I finally cleaned the extractor by taking out the extractor pin halfway out from bottom up.I believe the extractor stuck in the closed position there-by hitting the rim and causing it to fire. No problems with doubling now. I now try to keep the bolt clean and I now use a 22 bore brush, and a 17 caliber rod for cotton patch work, but I believe I still have lead stuck in the barrel. I might have to use Brownnells lead out screen to get that lead out.
