big5 got em. $469!! not the OPS version, but get em while they last!!

[riflem16a4]

yea might get one. still thinking first

[tempdrummer]

They had the m16 version for $399 the last couple weeks. I'd wait til they offer a better sale on the m4.

I'll do a quick pros and cons

pros
1. carbine, about ~29" length total w/ stock collapsed.
2. Very reliable operation with benefit of adjustable blowback spring to accommodate different ammo loads.
3. As accurate as the ammo I use and my own abilities
4. Metal receiver w/ excellent lines, tough finish and great looking Colt stampings + many parts high grade anodized aluminum outer parts.
5. fore grip accepts cheap rail adapters along top and bottom, not for suitable for optic mount. but great for vert grips, lights, etc.
6. Robust, same weight as an m4
7. mil spec bayonet lug and birdcage
8. excellent quality magazines.
cons
1. after optics and accessories can weigh upwards 10 lbs. For a .22lr its unwieldy compared to over options
2. main receiver is not a mil spec aluminum. As long as you follow the directions regarding field stripping should be no problem.
3. dust cover, bolt lock, Bolt slam thing, forget what its called, are purely there for looks, Although it is quite easy to get the dust cover to stay shut and still open easily.
4. trigger grip, muzzle attachment require additional parts or machine work to swap with aftermarket.

Sure lot more pros... Than cons. Lol
Long story short, it's a cheap fun way to shoot.
Having the look and feel of the "real" one.

I don't know... For that much, I'd just pay the extra $150 or so to build an OLL and buy a dedicated upper.

Forward assist?!...yeah purely for looks to mimic the real deal... nice pros and cons...

I wouldn't. 22lr is generally more dirty and you'll be shooting alot more. blowback is the simplest and most reliable mechanism for 22lr. ar-15 conversion uppers have iffy rep. And a good one certain aint gonna be $150.

[Droppin Deuces]

Iffy? The two I've had/have worked flawlessly. You aren't thinking that .22 uppers work differently than any other .22 are you?
And for about $550-$600(the extra $150), you can build one that is better than the Umarex and ultimately more versatile.

Who said an upper costs $150?

[iskra31]

Right now I have a standard AR-15, just bought a CMMG .22LR dedicated upper receiver for $460 shipped. Has correct barrel twist and all that fun stuff. Will be getting it tomorrow, so I'll post a report when i get back from the range.

he didnt say the upper was $150 he said the difference between the colt and a dedicated .22 OLL build is approx $150.

Second, You've got facts mixed up. The dirt from the .22 is a problem with clogging the gas tube on a CENTERFIRE upper when using a conversion kit and switching back to centerfire. It has no bearing on how the .22 shoots.
Dedicated uppers don't use a gas tube.

All .22 semi autos work via blowback. Even the conversion kits.

ah. I didn;t realize there are blowback uppers. still, $450 for the CMMG, you save on the DROS, tax, and waiting period. Versatility for the cost of a lower. Either way I suppose.

Its definitely gonna be a few more dollars and a little more work. Either choice is gonna be a ton of fun

You are getting your CMMG uppers from the wrong source
A CMMG upper is made from real AR parts, correct .22 barrel, stainless bolt, forward assist(a real working one) bolt hold open, anodized to match a real lower.
These were originally developed for L.E.O. and military trainers.
Very reliable as are the CMMG conversion kits.
These are not your same old conversions and uppers. Lots of R & D went into these and continues. I know, I've tested them before release and for the last year.
My M4 LE test rifle has over 12K through it with 3 FTE's not ammo or mag related.
