What caliber should my new AR be?

[Trigger Time]

I voted 300 blackout rifle. But I think you should build a shorty 300 blackout pistol and put a sig brace on it.

Im going this route myself

In my opinion, the AR platform is the best semi auto rifle. My sweetheart is my Rock River in 7.62x39 !

I voted bacon in the poll, but legitimately, I would look into a .308Win or .338 Lapua. Go big or go home. This, of course, assumes you bought an AR-10 lower and not an AR-15 lower.

Edit: Just looked up the dimensions on the Lapua round. … nevermind.

Personally, I would keep any AR style rifle for defense and in general shooting. If I were going to hunt deer, I would buy a specific rifle for that. Whatever you do with your AR caliber quest, if you are going to use it for deer hunting, make sure whatever caliber you go with fits within the parameters of overall cartridge length and type.

Yes its an AR-15 lower. Ive been thinking 300 Blk pistol with the sig brace. Anyone know if theres any regulation on pistol buffer tube length? Are they the same length as a adjustable tube?

Bacon and 300 Blk are tied. never can go wrong with bacon! Can bacon grease be used as gun lube? LOL

6.8spc pistol.

That's what I'll be hunting with next season.

6.8SPC not legal deer hunting cartridge in IN unless something has changed. So you're hunting out of state I assume? You may not be hunting deer or in IN for that matter.

Its a pistol and legal for deer in Indiana.

 

[youngda9]

I thought IN required 35 caliber minimum and maximum 1.8" length of brass? Can someone link me to where the laws have changed. Or are there different laws for pistols?

 

[95wrangler]

Cant link but regs are 4 inch barrel minimum, 243 cal or larger, case length min is 1.16 inches, no fmj bullets, can have up to 18 inch barrel but not designed to be fired from the shoulder. Straight from the DNR handbook.

The purple text!!, exactly how the media makes guns sound

6.8 is a phenomenal round... except you can't find it a lot of times. Supposedly its gonna make a come back.. but we shall see

A few months back I picked up some Federal MSR 115 grain 6.8 from Wal Mart. They had probably 20 boxes at the time.
