re: :Clames: :Propagandalf: AR help

My HOR is Shreveport, I'll be in the area visiting early next month. It's good that it's a surface you won't see unless you take it apart. I'm not a fan of the set screws going straight to the receiver though, might take a pin drill and make some divots so the screws have something to go into a little. It's going to scuff up the finish on the receiver anyway. Take time to make lots of test fits, better it fits snug and scuffs the finish than relying on the set screws too much. Looks like something that will have to be checked a few times as the rifle heat cycles too.

ETA: How much clearance do you have between the top of those tabs and the major width of the receiver in that area? Might have to relieve the tabs a bit on top to clear, hard to tell without seeing how much taper there is.
