.270 AR Build
« on: April 14, 2019, 10:05:04 PM »
My question is, can it be done? Would this be the same lower as a .308, M5? Thanks in advance for any info.

I think @Yorketransport did some kind of a 270 short casing to fit the AR platform.

I had an upper in 270 AR for a while and now JPharcher on here has it. I just talked to him the other day and it’s still up and running.

It’s a very cool little round and it fits on a standard ar15 size lower. Brass forming is a little involved and takes some practice, but it’s not bad. With all the new brass options for the 6.5 Creedmoor parent case you’ll have a lot of choices for quality brass to form.

The 270 AR has been all but abandoned by everyone; I’m told it involves a dispute around the proprietary bolt head that was required to use the .473 bolt face in an AR15. The 7mm Valkyrie and a few of the other rounds designed by Maddog Weapons systems are doing well though. He was involved in the development of the 270 AR and has moved on to his other wildcats now.

Look into the 6.8 SPC. It shoots a .277" bullet and i have friends that love shooting deer with them. the only problem is they are relatively proprietary with uppers, lowers and mags.

Agree that 6.8 is the way to go. Lower is actually the same so though. You can swap a complete upper with a standard AR and only need to change the magazine.

The 6.8 SPC is the easy option, but the 270 AR beats it by 150-200 fps in the same length barrels. I’ve shot the 6.8 and the 270 AR side by side out to 900 yards and the performance difference is significant.

Sure you get some more power on paper but no one is shooting a deer that far. I doubt any deer will notice the difference at 3 or 400.

i wouldn’t say no one is shooting deer that far. Most cant/won’t shoot deer that far.  There are many reasons for wanting that extra performance.

.270 is a long action cartridge so wouldn't fit in an AR10 pattern rifle. That being said I think it can be done. I have shot a 300 win mag AR made by Nemo Arms. I think Noreen Arms makes a 270 AR as well.
