I need to know difrence in MOA between 10,5 barrel and 16 inch barrel.
Thanks

I know what MOA is, but thanks for your time.MOA = minute of angle. It is roughly 1" @100 yards. A group of shots that fit into a 1" group center to center is said to be 1 MOA. Angles are measured in degrees. Degrees can be further divided into minutes (60 minutes per degree) and minutes are further broken down into seconds (60 seconds per minute). Think of two shots at a paper target set at 100 yards. You fire one shot and then fire a second and angle the firearm 1 minute from where the firearm was when you fired the first. The two holes will be 1 moa. On the paper they will be approximately 1" center to center.
A rifle with a 16" barrel may be more accurate than another rifle with everything identical except for a 10.5" barrel. How accurate would be an impossible qustion to answer due to the lack of other specifics in your question.
I am talking about M4 with 16 inch barrel and 10,5 inch barrel, and i need to know accuracy let say 300m. If somebody know in MOA the difrence between this two barrels with grooving 1:7. Thanks.

Is that something one can simply calculate? All variables would have to be identical: identical guns and ammo except for barrel length yes? If MOA is X from the gun with the 16” barrel at 300 yards, can one simply calculate the MOA of the 10” with any real accuracy? I don’t believe so, but I am not well read enough to give the definitive answer to that, so I am asking as much as pondering the answer. Never attempted to hit a target at 300 yards with a 10 “ barreled AR, but I would imagine the MOA would be approx 2-3 feet:eek:
So one could say that a 16" barrel should be more accurate than a 10.5" barrel. You can not say across the board that a 16" barrel will group X.X MOA and a 10.5" barrel will group X.X MOA.
Exactly..... MOA never changes. Just what you shoot whether it is MOA, Sub MOA, or a large grouping is what changes.
Without getting into too much ballistics, I can tell you that most rounds become ineffective with a 10.5 inch barrel. The round doesn't get the velocity it needs, and apparently starts to tumble and become ineffective after 100 meters or so.
Ah, well that is another issue of course. There was an interesting conversation on just that topic in this thread if interested:

We talked about the issues of the M4 vs standard issue m16 on the above loss of effective terminal ballistics, much less a 10" barrel

Ok, thank you.
I red somewhere that there is big difrence between 16 and 10,5 inch barrel about 3MOA. We have Mk262 ammo.
I am interesting about M4 (COLT)with piston and HK 416. Now we are trying to find out which barrel will be the most suitable for us. It is mean, for more tasks like CQB, .... We already have a lot of machineguns for longest distances SR25 and AWP .338 Lapua Magnum but we need something universal and compact for operator. Do you know what is the shortest barrel for M4 with M203?
but the 14.5 is a better universal barrel.
