Yeah, I always get stuck with the trainers. Owned a trainer airplane at one time, have a helicopter trainer right now (but it’s just a flying model).
The M69 I feel very comfortable with, for some reason, like I used it as a kid. Very simple and straightforward and everything’s intuitive (except for disassembling the bolt, maybe). This particular unit seems to have had lighter use than many.
Ran across these while knocking around, if you need some spare mags for the M69. taiwanese made, though. lot’s of good stuff, including some nifty milsurp rifles, at the site, if a bit overpriced.
