NS-522 Weak Ejection

Log in to see fewer ads
Picked up an Kengs NS-522 from a forum member on this site - and some spare factory magazines that cost more than I'm willing to admit, haha.

The rifle is definitely capable of shooting accurately, but I ran across two problems with it:

Firstly, only the magazine supplied with it will lock into it. The others appear to have a too narrow magazine catch. Should I file open the catch hole on the other magazines, or is this problem with the magazine?

Secondly, when firing the rifle for the first time yesterday, I found that the rifle had extremely intermittent ejection. The rifle will eject live rounds very enthusiastically; just tugging the bolt slightly out will spring the live round out. However, the rifle will eject empty casings only sporadically - even working the bolt briskly back, will often just flip the casing backwards and leave it on top of the magazine.

Any tips on how to solve this problem? For reference, I was using Federal Automatch 40 grain (in the 325 round white bulk packs).

Have you taken the bolt extractor/ejectors and cleaned out the old grease? That a common issue with these oldies.

Have you tried CCI Standard Velocity yet? Mine absolutely loves it, most of the time it shoots them into the threes. Not sure about the ejection problem.
