So I just ordered a Mega billet lower for a new build. Thing is I'm waffling on what caliber. 5.45 or 7.62 for cheap ammo, 6.5 Grendel for long range or Beyowolf(sp?) just because, or stick with 5.56 for standardization. What do you guys think?

7.62x39 is my OPINION.

Get one of each!
5.56 - all around general purpose round, can drop in .22 kit for each cheaper fun.

5.45 x 39 or 7.62 x 39 - great cheap shooting.

9mm - cheaper sub 100 yard plinking

6.5 ammo is expensive but from what I've read it's good long range capability.

LOL.......thanks for restating my question. I'm not interested in 9mm, but I do like the idea of a .30 cal. upper(7.62)

how many other ar's do you have? if the answer is zero, then i would suggest doing the first in 5.56, so you can see how the rifle is supposed to feel. i think 5.56 is perfect for the gun, so both of mine are in that caliber. i have other guns for long range. but in the end, opinions are like a-holes. everybody has one, and they all stink.

Haha this is so true. I have a 16" middy in 5.56 sooooo.

Either a different caliber or perhaps a 14.5 carbine(5.56) with pinned hider:yes:

i like that i can stock up on one caliber. i am one gun away from having only .223 and .308 rifles, but i just cant bring myself to get rid of my 1903... if you really want another caliber, go for a cheaper one. at least, thats what i would do.. :D

IIRC the Beowulf is only accurate out to little over a 100yrds, so I don't know how "long range" you can go with it.

If you've already got the 16" 5.56, then you should look into the 6.5 Grendel. Otherwise, you can always upgrade your upper or barrel to shoot heavy 5.56/223 OTM. Yes, you can do 4-500yd like everyone else.

7.62x39 on AR platform is a waste of time, energy, and resources. :D

I meant 6.5 for long range bud

sevensix2x51, I do already have a bunch of .223 so that is a bonus.

1988, could you expound on this a little. Is it cuz Sks's are cheap?

How about a .450 Bushmaster?

They are in stock at Midwayusa.com and they will ACTUALLY ship that upper to Kalifornia.

I got one and love it. Shooting off of a bag rest, with factory ammo and an Aimpoint Comp M/L 3 2 MOA dot optic, I put three rounds just under 2.5 inches at 120 yards. Those things shoot great!!

The recoil is a pretty good thump too!

Best,
