Hello, I believe I need a new slide based on the info I found on this awesome sight! I noticed while shopping for one that there are different "types" and obviously different manufactures. This carbine is already a "mix-master" and I really just am making it into a nice shooter. Will any slide mix with any bolt or receiver? Assuming it's all USGI of course
Yes, any type or manufacturer will work on the M1 carbine, but some will work better than others. All slides are forward and backward compatible with the exception of M2 application. There you must use a Type 6 slide. Early slides had a less dependable slide stop configuration. Later slides had a thicker arm joint and were less likely to break. Also, the later slides improved extraction reliability and ejection angle. I would suggest using a Type 5 or later for your shooter.
