Hi,
I have 2 CMP M1 carbines: an Inland and a National Postal Meter. Neither has ever been very reliable and I'm trying to track down the problems. One will leave brass in the chamber and when you close the bolt and retract it, the extractor just slips over the rim. It doesn't rip it off, just has no purchase. So I figure new extractor spring at minimum. Possibly new extractor.
Both will fail to feed and stovepipe, catching brass either under the lip of the op rod or lengthwise between the bolt and the receiver (while trying to chamber another round). I get jams with GI 15 rounders with fresh Wolff springs, new KCI mags, UU marked 30 round mags (Korean new I think), factory ammo and reloads of various powders.
I feel I've eliminated enough variables in the ammo and mags that the remaining problems are with the rifles.
question: wolff spring kits from brownells at $17.99 worth it or is there a better deal? the wolff kits include a hammer spring and sear spring but IMO all I need is ejector, extractor, and recoil springs.
