valve o ring?

OP,

I have to say that you are having some strange, chronic luck with dubiously modified valves.

You'll definitely want the correct o-ring first (think it is 1mm x 20.5 [ID]), and to make sure the threading isn't damaged in any way.


But as far as you are concerned, in its current configuration I wonder how well (or if) it will function.

First, with the power tube pushed forward the bolt will likely now sit into the breech. It may not be a lot, but it may inhibit feeding.

Second, and much more importantly, there may be an issue with proper sear lockup, given the bolt is now forward of where it was designed to be, and may behave like a pump mag, except that you cannot recock it.

None of this will be much problem if you can get everything sorted out with a new o-ring, but again, I'm bothered that someone just sold it like this.

To your question about it being this way owing to possibly sitting for a decade, no, for two reasons: (1) the original o-rings are red, and (2) the practice of cutting these open and using efficiency inserts didn't really come about until about five years ago.

i really appreciate the knowledge.. you help make the mag community what it is
