I just orderd one of these what does everyone think of them? Also it comes with a vertical sling mount, mag spring, and funny looking high visable follower.

How is the quality or the wilson spring and follower and are they reliable?

In the picture it don't look like it has a hole for the barrel detent, does anyone know for sure if not what keeps it from loosening up?

It don't matter it won't fit, the vertical sling mount that is made on the extension hits the barrel and wont let it screw on because it tilts the extension at a angle, also the spring they sent me appears way to long like it is for a 2 shot extension.

I just installed on on my Norinco 14 incher.  It fit just fine and dandy.  The threading is tighter than the factory cap.  The spring is a little tricky to get in, but it wasn't anything too difficult.

On mine, yes, the handguard/sling loop does make contact with the barrel, but it didn't interfere with the fit to the mag tube.

Just contacted Wilson and sent it back they said that they most likely left to much material on the sling plate and said as for getting a spring made for a 2 shot instead of the 1 shot is very possible and it has happend before. They are going to send me a new one that has the sling stud made in the front of extension. I'll try again.
