I was lucky and bought 3 AR lowers just before all the mess. I sold one to a famly friend for the price of a back ground check. I was going to sell the second one and keep one. I have been offered locally upwords of 300 for one of my lowers. I decided to keep 2. One I am building a A4 rifle. I like the 20 barrels and I carried a m16A2. I have the furniture and BCG. I found me a trigger group and installed on the lower. I could build me a carbine which I have considered.
Close friends have suggested building a 6.8 spc. or 6.5 grendall I even thought maybe a 6mm-.223 and use strickly for coyote hunting. I already have a savage axis in 223 and my 12 yr old has repeatly tries to claim the rifle. My brother has suggested the 300 black out. I like the black out becasue I can use my AR mags and same bolt as an AR just need the right barrel.
What caliber would you build on the AR reciever.
