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.

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.

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?

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 :D

You are getting your CMMG uppers from the wrong source:D
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.

I ordered mine direct, but I think you can get them from Riflegear now as well.

Can you drop in any AR-15 quad rail system to this M4?

M4rk
04-18-2011, 1:38 PM
Ya, I think u can. The m4 OPS version already comes with one.

SuMoSam
04-18-2011, 2:54 PM
Does anyone know if the Leaper UTG quad rail will fit on the M4 carbine? I'm ready to buy them on CTD, but don't want to buy something that doesnt fit.

The CMMG uppers use standard M4 hand guards. Any hand guard made to drop in a standard carbine will fit the CMMG as it's made from standard AR parts.

I bought the Colt M4 Carbine and not the CMMG dedicated upper.

Does the Colt have a delta ring assembly?

SuMoSam

Yes, the Colt does have a delta ring.

If the Colt has a functional delta ring and cap, a drop in should work fine, so long as it's a standard carbine length.

the difference between the m16 style .22lr's Big 5 has on sale is the smith & wesson 15-22 and the Colt/Umarex one. Keep in mind they only carry specific models that are accepted by their own buyers/managers of the hunting dept. No 15-22 MOE for example, I got mine from Turners.

I have to tell you all, the S&W verison is super light since its mainly made of the glass polymer type of stuff Glocks revolutionized. Unless you mall ninja it out with a super huge scope, lazer, mega lumen light etc the M&P 15-22 is superior.

also the M&P has a functioning bolt-catch with out any fake forward assist, the colts don't have the bolt-catch but have the fake assist

the earlier pros vs cons I think only where applied to the colt/umarex m16 .22lr version

i purchased the ST-22 M4LE from Spikes tactical...a dedicated 22lr carbine*. it will accept centerfire uppers...i got the 5.56 upper for it.

once the diet of ammo you feed it is sorted out...no problem. and you can get different springs for the blow-back operation should you so desire.

cleaning and maintenance are no more than that of the 10/22. in fact, it's easier to disassemble than the 10/22. (that's a reason why i prefer it over my 10/22 now)

the complete carbine was in excess of $800.00 plus shipping & DROS. it has a fully operational forward assist, too but no bolt hold open feature once mag is removed. the 22lr dedicated upper may NOT be converted to centerfire without a complete barrel change. (even then, I'm not sure it can be done)

*this carbine is a true mil-spec AR/M4 and can use all the AR accessories on the market you want.

by the time i finished the purchase of the basic ST-22 M4LE and 5.56 upper to go with it, it was into the $2,000.00 range...but worth it to me.

but, hey, IMHO, you generally pay for what you get...quality usually will cost more.

Spikes discontinued and pulled the ST22 from shelves due to quality issues.
