I have a 5.45 demilled parts kit on the way from K-Var and plan to have a krink built into a SBR. I contacted several Class 2 builders recommened by this forum to get some prices on the labor to do the build and refinish. I believe I'm going to have it built on a Global Trades 1mm stamped receiver which costs about 75 bucks in the type 2 configuration (the least amount of finishing). Global doesn't do builds anymore, but they recommended Hector Bennett of Elk River Tool & Die. They said they trained him. I talked to him, and he said he could do the build for $400 ($125 of that is to do the side fold cuts for the trunion) plus $150 to park and then paint, so $550 shipped back to me. I thought that was reasonable. I was wondering if anyone here has had work done by him before and/or if you have a krink built on a Global 1mm stamped receiver, and what your opinions are of it. Thanks in advance.
