What caliber/barrel length would you choose if you already had a 11.5" in 5.56?

Torn between another 5.56, 9mm, or 7.62x39??? I have different firearms in all 3 calibers.

Opinions will be appreciated.

Thanks
 
Well here on the EE of course! Ive already got one in 223 as well so my next would probably be a 9mm with around a 12 inch barrel because my range doesn't allow anything bigger than 223 other than pistol rounds
 
Where? Well that depends if you want the highest quality or the cheapest? My vote goes to Tier One Armoury in Edmonton, they usually have uppers and lowers in stock along with everything else you need to put an AR together. Anything they don't have they will order for you.

For AR's my favorite length barrel is 12 inches but only you know what you like so...

Caliber? Since it's restricted I see no point in shooting a fancy new treat of the week cartridge looking for more terminal performance.
But, if you want to build a target rifle I'd probably go with 6.8SPC or 6.5 Grendel but if you just want to run a pile of ammo through it at the range having fun banging steel plates I'd probably go with 9mm since you already have a 223.

I own a 223 and a 9mm AR and the 9mm is really fun and cheap to shoot.
An AR in x39 has never appealed to me, just seems wrong to put it in an AR, especially if you want to run corrosive through it.
 
You can also build one from EE parts, I have, easy to do and I am not very handy. I would go 9mm for cost/close distance shooting and .223 if you want to stretch it more. Barrel 10.5-14.5 have universal appeal (i have 7.5"-16" in 3 cals). Building is fun and allows for you to get exactly what you want. Cost wise vs the exchange it is about the same but getting exactly what you want and put together with your own hands is the big plus.
 
I'm with Mr.12gauge! For me, building is almost as much fun as shooting them!

I learned a lot about AR's by building my first. Only downside for me was rushing the build cause I wanted to shoot it... At least you have one now, you can take your time and get exactly what you want.

16-18" would fill another role for you, with an optic it's a lot of fun to stretch out. We're lucky to have steel at 100, 200, 300 and 400 yards. It becomes a game to see who can ring all 4 the fastest or play horse to see who's cooking.. haha

9mm might be cheap but it just doesn't do it for me personally. I prefer a pistol for that. :puke:Kriss

PWS 7.5" in 7.62x39 is a lot of fun to shoot. It's a piston system. Not cheap.

Even with blast mitigation device/flashhider still throwing occasional fireballs with Barnaul ammo though.
 
I agree with build it yourself. Down the road you might wanna upgrade parts to like those SS barrels, Nickle Boron BCG or adjustable gas block, BCM/Raptor charging handles etc etc. Then why not just get them now and build your own.

I have a few of both 7.62x39 and 556 I have to say that 556 runs more reliable in my experience. If you are just plinking and think 7.62 is cheaper ammo then, sure, go for 7.62. I just found that 7.62 bolt (just the bolt) and extractors are a bit harder to come by (not impossible to find still). Plus there are not a lot of choices for 7.62 AR barrel compare to 556 or 223 Wylde

Building a 9mm AR is a lot more expensive than building one in 223. There are a lot more hard to find parts.
 
I recall you getting my Bushmaster 9mm for a fair price if this is the same person and there was some re building to do there (if not the same buyer my mistake).
You are correct though, I did source another 9mm for a good price on the EE, when cost of ammo is factored 9mm pays for itself even with the added build costs compared to .223

Yes, that was me. With a new receiver it's been running like a top ever since and is still in my collection. You gave me a great deal on the parts and I appreciate that but it isn't the norm. The 9mm specific parts typically draw a premium price new or on the EE.

The reduced cost of shooting 9mm is great but you also have a greatly reduced capacity for shooting. By that I mean that with my 223 AR I can easily ring steel at 300 yards and with the 9mm 100-150 yards is approaching it's limits in regard to shooting accurately. Not a problem if that's all you want to do and I really do enjoy shooting the 9mm but it's not just about the cost of ammo unless you are limited by the range you shoot at or shoot primarily indoors. It's a trade off, I get around it by having more than one AR but not everyone wants or can afford multiple AR's.
I probably wouldn't buy a 9mm AR if it was the only AR I was going to own (unless I never shot beyond 100 yards). As a handloader the cost of ammo is less of a concern for me so I may be in a slightly different situation than some.
 
I have a lower I want to build a 300BLK

I have a ton of 208g AMAX Bullets that would be fun to shoot

I've owned four different rifles in 300BLK over the last few years and loaded for all of them, let me know if you want some suggestions to get you started with the 208's. Start shopping for A1680, it's my go to for subsonic 208's in a semi.
