Spare parts for 5.45 AR

[handyandy]

I want to use my 5.45 AR (S&W upper) for some classes this year, so I want to have a complete spare bolt and a second, loose extractor. Even if I do have a complete spare rifle, I like to have whatever parts I need to fix my primary rifle, should it go down. Smith prices on parts are ridiculous and I don't think they will sell a bolt loose. So who else sell quality 5.45 bolts and extractors? I know Model 1 does, but their parts don't have a good reputation. I sent an e-mail to Ballistic Advantage to get his price on a complete bolt and loose extractor. Anyone else?

Thanks, Andy

You might want to check out MGI - they have a 7.62x39 and 5.45x39 quick change barrel/magwell swap.
