Tacticalgenius Posted April 5, 2012 Report Share Posted April 5, 2012 Hey everyone,I was in the process of finishing up my MA-ten build last night (or so I thought) when the trigger pins from my DPMS LR-308 LPK decided to keep going out the other side of the receiver with no resistance! Just wondering what size the MA-ten trigger pin hole is and what trigger pins work best. FYI, I tried some RRA trigger pins that came with a 2-stage trigger and they won't fit, too big. I am assuming that the RRA are .156 and the DPMS are .154 (from what I read about), so I guess a happy middle ground would be these, http://www.midwayusa.com/product/857672/kns-hammer-and-trigger-pin-2nd-generation-2nd-modification-non-rotating-ar-15-small-pin-oversize-1555-stainless-steel?cm_cat=Cart&cm_pla=ProductDescThanks for any help!

Matt.Cross Posted April 5, 2012 Report Share Posted April 5, 2012 MA TEN has small pins. Only Colt receivers use large pins, AFAIK. Quote Link to comment Share on other sites More sharing options...
survivalshop Posted April 5, 2012 Report Share Posted April 5, 2012 Did you install the trigger/spring with the pin ? Most pins will go through the receiver with out a trigger/spring to give it resistance & of course the "J " spring in the hammer keeps the hammer pin in place , as does the hammer spring keep the trigger pin in place. Pins should have groves in them for this purpose .Some may be tight & there should be some slight resistance. Quote Link to comment Share on other sites More sharing options...

I did install the trigger assembly with the supplied pins. They do fit better, but I am still able to move them with a slightly firm push of the finger. I hope they don't walk out on my at the range. Jason from Mega said to try the KNS .154 pins. I will try them if these walk out on me. Thanks for the help!TG Quote Link to comment Share on other sites More sharing options...
