I’m new to ARs, don’t own one yet. I like the Seekins SP-10. I contacted Seekins after watching a video they created to show how to adjust the gas block to get ideal spent cartridge ejection patterns. I noticed one of the 2 set screws which attach the block to the barrel, was sticking out further than the other. I suspected only one of the set screws was dimpled into the barrel. Seekins confirmed that is the case. Is this an issue for securely mounting the gas block? I can’t imagine a set screw butting directly into the side of a round barrel, creating appreciable retaining force? The contact area would be infinitesimal because the barrel is round and the set screw end has to be flat. The intersection of a flat plane with a cylinder is a line at best. For people that build ARs here, are the set screws normally both dimpled into the barrel ? I don’t see how a non-dimpled set screw could work. I appreciate any experience here as I am new to ARs. I was ready to buy the SP-10 in 6.5 CM until this design feature bugged me. And then these rifles have become scarce with the store I was ordering from. Back order only right now.
