So, I purchased a Mega billet lower of the local Virginia gun trader. The seller already had assembled the lower but didn't connect the ambi bolt release. The lever is located right above the magazine release. I have seen this setup on other ambi billet lowers as well. The normal bolt catch works properly. I think it is just missing a spring and detent (2?) between the normal positioned catch and the ambi side on the right.
My question is, what do I need to fix it? Are the spring and detent special snowflakes? Where can I purchase them or what should I search for? My google-fu hasn't come through for me this time. I feel like the selector detent and spring would be the correct size, but I am not positive.
Thanks guys.
