I have a thompson contender barrel from SSK in that caliber and it works very well. My Order will be in ASAP for an upper for my AR lower.......:o) Is your AR upper going to be in .270 JDJ, or 6,8? How much barrel/ configuration? And what weight bullet and rifling twist are you looking at? Inquiring minds are downright fascinated; I've got a similar 276/140 grain wildcat project of my own going on....
The AK series is a weapon system to be reckoned with.
The big problem is "It wasn't invented here"
Truth, noone gets 500meter acuracy out of this beast. But, it fires every time the trigger is pulled.
What grunt could ask for more?
