Couple of quick questions

[stag88]

Hey guys had a couple of quick questions. First will an ar15 function without a bolt catch, know it won't hold back on last round but will it function normally? Next is at how many at how many rounds through a lower until it is recommended to replace a mil spec action spring? And lastly I'm trying to sell some old parts what's a fair price for a slightly used Troy Inds modular combat grip and a cav arms mid length hand guard?

Will a clock work with only one hand?

Buffer springs are measured. Use the search button and you will find the information you seek.

Are you having a hard time finding a bolt catch and therefore considering doing without on a build? Or are you just curious?

I'm getting lots of wear on my current one, I think it's because of my blocked 10/30s(California) which are causing the lugs? I think, to drag across. Because of the panic I can't find Any of the small replacement parts I was planning on
