I just got done installing this trigger on my post ban Bushy M4gery.  The kit comes with "oversize" hammer and trigger pins, which I went ahead and used.  They were pretty tight going in,  and now I'm wondering if I should have re-used my old pins.  Not much I can do about it now, just wondering in case I do another one of these.  All and all I'm real happy with the trigger, btw.  Much nicer than the factory Bushy trigger

I have an RRA in a Bushy also, the pins are tight, but will wear in with time(read shooting), next time use some good Lithium based grease and it will help the pins go in smoother

u will enjoy the rra trigger!. if u want it tuned precisely send it to john holliger at whiteoak.com
