I just bought a Windham Weaponry AR-10 and want to put a RRA Varmint trigger in it. Are the AR-15 and the AR-10 triggers interchangable? This is the first AR-10 I've dealt with.Thanks, Chuck.

Probably, yes. I've put aftermarket AR triggers in both my Armalite AR-10's, and they work fine. I say "probably as the -10's aren't as standardized as the -15's.

Triggers should be the same. You can get a heavier hammer if you need it to light off hard 7.62 military primers.

Thanks for the replys guys. Ordered a RRA Varmint and will see if they are interchangeable.

Hammer, trigger, pins, and springs are supposed to be the same in both.
