M4 Off-The-Shelf?

[CKettler]

What off-the-shelf manufacturer/model AR is most like the current issue US Army M4? So in the best case, I would go into a store and buy this weapon off-the-shelf, and it would look, feel, and operate the same as the US Army M4A1, less full auto.

I apologize if this has already been discussed, but I could not find the topic in my searches…

Colt 6920…

[DocBach]

If you get a 6920 you’ll need to add a KAC M4 RAS, too.

[Garrasa]

our Pltn has FN M4 carbines, personally I think an LMT standard with either ACOG, EOtech 553, or Aimpont M2, and a KAC flip up rear sight and RAS would be closest to what we’re issued

Colt 6921

[shittercrewchief]

yup 6921 with a M4 RAS added

Colt 6921.

C4

Yup, 6921. IINM, it’s exactly an M4 minus the select fire feature and govt. roll marks, of course.
Although, to quote your post, “…and it would look, feel, and operate the same as the US Army M4A1, less full auto.”, Any other good, “TDP adhering” M4 upper with a govt. profile barrel configured as an exact Mil clone should look, feel and perform the same as the real thing, if you will.
Sorry to derail the thread but a quick question to Garrasa-- are these FN M4 uppers sitting on FN M4 marked lowers or colts sitting on FN M16A4 lowers? Photos would be good too, if you have any. :thank_you2:

A 6920 is the closest without having to go the NFA route. Obviously Arizona is NFA friendly so that isn’t an issue. But, you will have to add on an addtional 200.00 for the tax stamp.

So ask yourself if the extra 200.00 is worth the slight change in barrel length. I don’t think it is. You would be better off getting a 6920 or a true SBR with a shorter barrel. YMMV.

I was under the impression the only complete guns FN is making for the Army are M16A4s.

Since you are already in Scottsdale go to the Scottsdale Gun Club and check out the Colt 6921. Last time I was there they had a few on the shelf.

[variablebinary]

Easy, Colt 6920

If not Colt, I personally would go LMT

from the looks of it, they’re overhauled M16’s re-marked M4 carbine. I’m not sure what the upper is, but when I go into work on Tuesday I’ll try and take some pics

I too was under that impression, hence, my curiosity about the weapons issued to Garrasa’s platoon.
I have heard of conversions whereby the lowers were even stamped over with m4a1 but cannot confirm the report’s authenticity nor was it stated they destined for field use.

Thanks! I appreciate it. I Guess that i report i read is accurate afterall. Stay safe.

[Eurodriver]

Ahhh, yes… the elusive FN M4A4 Carbine… You have to be pretty high speed to get one.

Or a 2111

[CKettler]

All,
Thanks for the great information and discussion. I figured that I would ask the experts, and as always, you guys really got into the details.

C-Grunt, I’m a regular at SGC, so we have probably run across each other before…just didn’t know it.

All your answers lie within: http://m4carbine.net/showthread.php?t=6642

But in short - yes, the same people that make the real M4 make their civilian M4 exactly the same - which is what almost everyone that responded to this thread has said.

@LowSpeedHighDrag

Does the Colt use an M16 bolt carrier?

Does the Colt use the low shelf on the lower receiver?

Does Colt block the lower receiver?

Does the Colt use milspec or commercial receiver extensions?

I don’t know the answers to the above questions.

I ask these questions because I was wanting the closest thing to the M4, however I was talked into buying a different brand of M4gery at a substantially lower price.

If I could afford it, I’d get a KAC SR15.

A quick look at Rob;s infamous chart will give you most of your answers.

A Colt 6920 is basically a 16" M4 with no select-fire. A 6921 is the 14.5 version and must have a pinned muzzle device or NFA paperwork.
