I picked up an SSA-E trigger from Primary Arms during their Black Friday sale... 
I threw it into my LWRC REPR and, after function checking, I noticed that my hammer pin is spinning. I am thinking that Fe/Ca on Al is generally a bad idea, and was wondering if I screwed up on the install... I did not over-tap the pins with my gun show special brass punch kit, but I am an electronics guy and am not sure if I messed anything up... The hammer pin should stay in place and not spin right? We are only talking about 10 to 15 degrees of rotation per trigger pull, but steel on aluminum will wear eventually... BTW, no shots fired. Function test only at this point. |

Well, I got the Primary Arms newsletter today and saw they have the SSAE's back up for sale ($179) and bought another one for the lower build I am doing for my Adams Arms upper. I also picked up two Spikes lowers and two sets of these: KNS Non Rotating Hammer and Trigger Pin Non Rotating
I figured I was placing the order anyway... Why not. I know you said it isn't really necessary, but I figured what the hell, it makes me feel better. 
Edited to add... DAMN YOU PRIMARY ARMS!!!!!!!!!! I am sleeping on the couch (again).

| Giessele does NOT recommend using KNS pins with their triggers. Read the instructions and they specifically mention to only use the hardened steel pins included with their trigger. If you are really concerned with the pins rotating, shoot them an email. They have great customer service and will be happy to answer any questions you have. |

Well, %$#%.
That is why I am here. If I had asked the forum's permission first, I would not be out $38.00 
Anyone want some pins? 
Seriously, I appreciate the help, guys. I am an M1A guy at heart and am still figuring out this whole black rifle thing. I am still in my thirties, so don't call me a FUDD.

Depending upon pin hole size sometimes HS pins will rotate and sometimes not. The pins are pretty hard and have a smooth ground finish so dirt will not imbed and the pin act as a lap. You and I will both be six feet under before any wear on the receiver ever happens. Call the shop if we can help further |
