Guys (and gals), I'm looking for reviews and input on a .22 carbine trainer.
My candidate platforms are
#1 - Sig 522.
#2 - CMMG AR-15 .22 upper
#3 - S&W M&P 15-22
#4 - KelTec SU-22
My thoughts so far, and where I'd like some APS guidance/referral help with....
#1 - Everyone seems to say the Sig 522 is teh awesome. Extraordinarily reliable. Runs great on cheapo Fed bulk pack. Reliable. Did I mention reliable? Controls are AR-ish, but not fully AR compatible. But they make a good trainer for the 556 rifle that Sig offers. I found one in town for $399 yesterday. I plan on building an AR/M4 later this year but if I find I like the manual of arms deviation it could sway me to buy a Sig556 instead of building an M4. Sig556 is a bit more expensive than an M4 though.
#2 - I found a CMMG .22 upper for $365 online. I can use my current lower, and eventually scrounge up a new lower to mate it with permanently, but that's an added cost. I don't like the "upper swap" game. I think a rifle should be a rifle, and I don't have any plans of having naked uppers lying around, so a lower WILL be a hidden cost in that $365 price tag later on. It'll drive me nuts otherwise. No knowledge on reliability reviews. Identical manual of arms to my AR, and future M4 I'll be building later this year.
#3 - It's made of plastic. Even the optics rail of the upper receiver. That irks me. The gun is VERY capable of being flexed from sling or bipod tension and sending groups way off from a rested zero. Seen YouTube vids of this. Heat has been reported to change zero, even for light recreational use. And I've never seen one complete an Appleseed without a reliability problem.
#4 - Never seen one. Reliability seems reported on par with the Sig522. AR-ish, but not quite an AR. VERY light. Bordering on too light for a proper AR trainer. MSRP is $400, which makes street retail probably $325-$350 range. Tempting.
Right now I'm leaning HEAVILY towards a CMMG upper, with straying thoughts towards the Sig 522.
What says APS?
