So I picked up one of the 80% receivers that were for sale here a while back and was wanting to build it in 5.56 either rifle or pistol. No I have not built one before, only owned one or two ak's before and they never stayed long. Thinking in 5.56 it may stay longer. Point is, is there a kit I can purchase in 5.56, I've done some searching but am unclear on what exactly I am looking for. Any input or help would be great. Thanks.
