I am looking at starting my first build from a kit. What's your opinion on a 16" CAR vs. a 16" Mid-Length CAR?

I am going to get a kit and I notice the mid-lenths aren't as as plentiful, as kits anyway.

It's said that a mid-length gas system doesn't send as much of a gas pulse back to the bolt carrier. Thus it is supposed to be less wear on the bolt buffer, spring, and butt stock tube. A mid length may offer better accuracy with iron sights as the front site is a bit further down the barrel.

I have a CAR and to tell you the truth I can't tell the difference in recoil or parts wear. As for accuracy I can still get nice groups with iron sites at 200yds with the CAR setup. I say get the CAR gas system as it's just as reliable as the Mid-length IMHO. If wear or recoil is a consideration, you can always put a 9mm weighted buffer in your CAR stock in place of the standard CAR recoil buffer (that is if you're running a CAR/M4 stock and not a Rifle length stock/buffer).

The extra money you would spend on a mid-length bbl would be better spent on a free float tube for a CAR barrel.

As far as the "wear"- how many rounds are we talking before this would be a factor?

i'm a midlenght fan now...it just looks better than the 16in carbine

Midlenght here. I think the short car stock just looks goofy on a 16" rifle. I also like the larger sight radius.

I have both 16" CAR and a 16" mid-length CAR and I prefer my mid-length.

I like the more rail real estate of the mid-length which have more room for my tactical light and hand if I decide to grab the handguard.

The mid-length is also more reliable in cold weather conditions.

If you're building from a kit, you might want to go for the CAR for now and do the mid-length later on.

Good luck on your build.

I have the Operator Mid-Length barrel - thread link

The mid-length looks more balanced.

+1 Midlength

Midlength positives: Looks better, longer sight radius

CAR positives: cheaper

Midlength negatives: Expensive

Car negatives: ?

Get BOTH...

Now that its out of the way...

Midlength here.

After researching and comparing prices for months I found that the cost difference between the two is rather small given similar quality.

RRA midlength upper (chrome lined) $429-$449
M4 Stock $59-$62
Lower parts kit $49-$59

Total midlength "kit" cost $537-$570

Del-ton M4 Kit with chrome lining, M4 stock and lower parts kit $530

Del-ton Carbine Kit with chrome lining, M4 and lower parts kit $520

Not much of a difference for what (at least to me) feels like a smoother cycling system (midlength).

I'm not sure as I've never heard of anyone wearing out a bolt carrier tube or a bolt buffer on a CAR. My guess would be 8,000 to 10,000 rounds or more.

If I were to get a CAR I would get a 14.5" barrel. If I wanted a 16" barrel I would get a mid-length. I just got a mid-length Sabre two days ago. Longer sight radius, longer gas system, more room to pile junk on the forend. I can't think of a good reason to not get a mid-length if you want a 16" barrel.

One reason would be weight. If you get a 16" Superlight weight CAR barrel your not luging around the extra weight of a HBAR, which most affordable Mid-length's BBL's are.

Second why cut your feet-per-second with a 14.5" CAR BBL? Unless you pay the $200 Tax stamp the 14.5" BBL needs a perm flash hidder attached to bring it out to the legal 16". At least with a 16" CAR BBL you can change the flash hidder to any sytle you want any time you want + gain a few ft-per-sec.

I really think the Mid-length's and 14.5" CAR BBL's are really form/looks over function.

What is the midlength gas port size? CAR is smaller than rifle to reduce gas in the system. If midlength is in between, I don't see why CAR would be less reliable than midlength. While our soliders use short barrel CARs in the battle field, we sure can live with 16" CAR in the range.
