CMMG 22 LR AR-15 Upper

YMMV...Not for everyone, but unlike the cheaper priced polymer ATI, this is an all metal upper

Here at Cabela's

The CMMG AR-15 Sierra .22 Caliber A3 Upper is a complete dedicated rimfire AR-15 conversion upper that maintains compatibility with all the same parts and accessories that fit your full caliber AR's. The 22 Long Rifle conversion bolt, along with the barrel's true 22 LR chamber and proper 1/16" twist rate, make for a truly accurate rimfire AR-15 for inexpensive practice, small game hunting, and introducing young or new shooters to the AR-15 platform.

CMMG's Sierra rimfire uppers feature many significant improvements over previous designs, enhancing functionality, reliability, and ease of use. Prominent among these improvements are an Anti-Jam Charging Handle, Live Round Extraction ability, and Gas Deflector. CMMG's durable Weapons Armament Surface Protection (WASP) Melonite treatment has been applied to the barrel and surface-hardens the steel, extending barrel service life by reducing friction in the bore and lessening bore surface wear.

The Sierra upper is ready to drop on to any standard mil-spec lower receiver, all that's needed are a compatible magazine and a pile of 22 LR ammunition to start enjoying some inexpensive and fun time at the range! Compatible with Black Dog Machine and CMMG rimfire AR-15 magazines (not included). CMMG recommends the use of Plated 40 grain High Velocity 22 LR ammunition for optimal functioning.

Green to this upper. CMMG is high quality stuff. This is not crap polymer or junk made and sold during panic times. CMMG makes really great stuff.

can someone please find a surplus of a m m o for this???

How does this price compare to previous prices? What were people getting them pre-hysteria on sale for, normal prices, any info would be helpful.

I have the money and have the want, but don't REALLY need this.

They are $449 when in stock from CMMG, so not a bad deal from a third party seller.

Extremely good reviews on this product. OOS as of this posting.

In for one yesterday.

Might want to check mag availability before purchase. I have an S&W M&P 15-22 (also ~$redonkulous price now) and new 25-rnd factory mags were going for $100 at my local gun show.
