Gritty pull - Elftmann Tactical ELF SE Precision Rifle Trigger

Looked like a great concept but in reality not so much. The design of the trigger tension spring needs to be rethought. With the captured spring and pin there are multiple friction points giving a gritty feel to the pull. The pin rubs on tha walls of its housing and the tip of the pin drags on the bottom of the rifles receiver. Sure I could have polished and greased the heck out of it to attempt to mitigate the grittiness. But for the price I shouldn't have to do added work to make it better than the stock trigger. Second point the original description said it came with straight and curved trigger shoes but mine arrived with only straight.
