Hello.
What do you think the shooting distance for a AR with iron sights is say with a 16" barrel and a 55g bullet.

thanks Brian

I can probably hit a tennis ball at 50 yards and a side of a barn at 800 yards.

55 gr bullet probably won't be much good past 300 yds. Need heavier projectiles for that. But the iron sights and 16" barrel won't hold you back.

Of course a lot depends on the iron sights. I have the Northern Competition rear sight with the NM front sight post. Aperture size on the rear is 0.042".

Well if you're a good shooter I'd say 400 yards. Of course, with iron sights I'd be impressed if I could hit man targets consistently at that range since I haven't had much practice.

But I've seen videos of carbines with good scope optics reaching out to 500 yards.

Just depends on your shooting capabilities. My Marine buddy hit man size targets out to 600meter with irons with an AR. Him and I can hit cantaloups at 200yds with my AK. Just depends on you.

I have seen a balloon hit at 300 yards that was about 12 inches in diameter. It took around 4 shots to get it in there but then was consistent. We also hit 20 inch military D targets at 400 yards and could easily do 500 yards as long as you know your drop tables. At that range you just need to know what your come ups are with that rifle set up. All of the information to make those hits are available, but you knve to know how to execute the fundamentals well. BTW for what it is worth this is shooting from Prone with a loop sling.

I shoot 55gr out of my 20" upper and can pretty easily hit 400 plates at Angeles. 500 ain't much harder, it's just very tough to hear it hit if anyone else is shooting. 600 is possible as well. Not sure how much is lost with a 16" — will try and report back as soon as I get mine in the mail :willy_nilly:

How big are the plates?

Given your proficiency, I would say with an AR's irons 300 yards sounds about right. Personally I am consistently effective within a 12" target at 300 with irons and 55 gr junk ammo(such as PMC, my favorite factory plinker cartridge). Honestly, if you can strike a man sized target at 300 yards, you're good to go. Anything farther is either irrelevant with a carbine or you could always use magnified optics. If you're shooting matches you likely won't use a carbine build any way, and most combat engagements with long rifles occur between 50-200 yards in most circumstances (any vets out there, please correct me if i'm wrong). If you want effective range beyond 300 meters, go pick up a M1A or AR-10. You ought not expect .308 performance out of a carbine chambered for .223.

Or just get a 6.5 Grendel upper and mags... that will allow you to slay for some serious yardage beyond what 5.56 is capable of. Supersonic to 1200+ yards as opposed to 5.56 which is around 600. It's a beast.

.308 / 6.5 / 5.56
