Thanks for the replys, yeah i jsut started reseraching here and itll take me hours to read through everything. I'm building a 300bo currently, and started reading about 7.62x39 in an AR and how its not as reliabled? do i have to purchase different mags and what not?
What other calibers am I able to build for my uppers that could be stuck onto my AR15 lower? I know I can do 300BO but tahts the extent to which i have knowledge in.
and don't forget, same BCG.not for .300 BO, same mags as 5.56mm or .223 remington.
7.62x39 cartridge has a pronounced taper to it. To get it to feed properly in an AR, you need a curved mag. Similar to what is used with the AK-47.
Parent case for the .300 BO is the .223 remington.
and don't forget, same BCG.
The only thing different when going from 5.56 to .300AAC is the barrel and muzzle device.
I wonder how many times somebody shoved a mag full of 5.56 into a AR in .300....
I wouldn't think the bolt would go into battery in a case like that. .30 cal bullet would only go so farPutting a mag of .22 bullets in a .30 cal barrel is not a big deal, you just ruin brass. With 110 & 125 grain bullets in the 300 BO you can get those chambered in a 5.56 barrel and that can ruin your day. Seen it done already. Shooter had to get a new barrel and drawers for that trick.

Very true. and with ammo prices around $17.00 a box not a bad caliber to plink with any more. I love this roundAR5.7 (5.7x28) is fun, too............
