I recently bought a AR15 built by someone else. I asked a friend to help me purchase it and he found one out of the classified. DPMS lower marked 5.56/.223. Not sure of the upper to be honest. It has a heavy stainless bull barrel. I took off the handgards and the barrel has no markings what so ever.
It shoots great and I have no issues with it functioning.
My question is "How can I determine the twist rate on this" so that I can select the proper bullit weight for this gun.
I have been just plinking with handloads of .223 winchester 55 grn fmj and H335
I can try to get a picture if that is needed...
