    I recently cut a blue insert in half and placed it inside the extractor spring seating area. No spring was used. The weapon functioned without any problems. How long would that last? I don't know. I certainly wouldn't use it anywhere but the square range...but it did make me chuckle.

    o ring and extra power springs were created as a response to the extraction problems the carbine gas system had. Middys shouldn't have that problem and arent required. I guess you could put it on but not sure what it would solve.

    I think it's safe to say you don't "need" it but OP asked if it will still work. I have to say yes you can use it anyway, if you just want to. I run a G&R Tactical bcg in my BCM middy which has the extra power spring, black insert and o-ring. I have had zero probs. So do you need it...no. Can you use it anyway....yeah if you want.

    O-rings can be used in midlength, intermediate and rifle length guns. BUT they do sometimes cause problems. These problems are feed problems and sometimes failure to eject problems because there's so much extractor tension that it's overpowering the ejector. I see these problems in customers guns about 2-3 times per month. People are fixing things that aren't broken. I think it was MarkM that once said that not everything needs a fix or something to that effect.
    The whole thing is a system. If you start messing with one thing you effect the other things.

    I had the bcg I mentioned as a spare and dropped it in the way it came. It was not a "fix" for a nonexistant issue or anything. I wanted to see how it performed and it has been perfect so far. So like I said you can use them if you want, however, they are not a neccessity. Not to say someone other than myself won't experience said "problems". I agree wholeheartedly with the whole thing is a system and when monkeying around with it things are likely to go wrong!

    To the OP, if you decide to try it out and have concerns then you now know where to start. Like gotm4 said sometimes there are issues. If you don't like the idea of trial and error then don't use the oring and you'll be gtg.
