I picked up an LMT lower from Denny's Guns in the EE. I got my RRA LPK from ADCO today and put it all together. Taking my time, I was finished in about thirty minutes. I had ordered the roll pin holders recomended in the guide section. I did not even take them out of the package. It was very easy to build. My one problem is that the selector is not real crisp. On my factory built RRA it clicks loudly. This one just swivels back and forth. It is not real loose, but it is not real tight either.
Any ideas?

Sounds like the safety detent isn't in place... Pull the grip, remove the detent and remove the safety selector... drop the detent back into the lower and put the spring and grip in place.  If the detent is fully seating it will protrude into the selector area...  It's possible there could be some debris caught in the channel, use a drill bit spun by hand to carefully clean the channel if the detent won't fully seat...


edited to remove pic... wasn't very clear...

Also add  just a bit of light oil whiel assembling to the detent hole, spring, and check the selector lever holes to ensure that they are deep and clean of finish, that should be it.

Yep, sounds like a detent problem, it's not engaging fully or something.  Don't forget to oil the detent and spring when you put it back together, I put a bit of lubricating grease in the slot on mine, works great.

Thanks for the advice guys. I reamed the hole, lubed the detent and it works much better.
