buffer tube /detent issue

[Disciple]

Would you not potentially run into the gas key contacting the receiver by doing this though? You're essentially shortening the RE by turning it in, no?

That is going the opposite direction; you would shorten the stoke and increase the gap between the carrier key and the receiver.

Oh, duh.

I would not feel good about shortening the buffer stroke. Not sure what a full rotation of the RE would yield, but I'd be concerned about it much more than leaving the RE as is in the pic.

yeah, that's why I'm not taking out the receiver and tightening it myself. it passes the 2 quarter test already, any more and it would be over shortening the stroke IMO... I'm going to wait and see what Sionics replies back with first.

The way I look at it is that if you can only turn the RE in far enough to barely make contact with the retainer pin then the stroke is probably on the long side to start with. However OP said in that config it passes the two quarter test, which has me wondering if the RE is out of spec itself.

Could be. But based on the pic, I'm doubful you could expect another full turn.

I'm betting the RE is a little shy of material in the front by the detent hole. But I wouldn't go as far as to change/replace it if it were my gun.

I've only seen the PWS enhanced buffer tubes with the notch. Always thought it was a good idea.

There is a downside to them. If you have a jam or your bolt carrier is locked back and won't go forward. With a regular buffer tube you can just unscrew it and take it off. However if it's jammed, that type with the little wings won't allow it to unscrew off of the detent. So you actually have to cut off the buffer tube to fix the problem

Hmm, haven't seen a carrier stuck like that before. What would cause that?

not stupid common but I've seen it... for example, the buffer detent and spring coming out during fire and jamming up the front travel of the bolt lol.

the latest time I saw an issue was where the forward assist roll pin broke and jammed the carrier in the rearward position.

not like it's an every day occurence, but the buffer tube with the wings would make a siuation like that more problematic.
