Magpul STR fitting kinda loose

[303hunter]

I’ve got a Magpul STR mil spec stock that still moves a bit, even with the friction lock. I’ve tried it on several buffer tubes with the same result. Is there anything I can do to tighten it up?

How loose? Can you take a short video? I'm not surprised, there's a lot of variation in buffer tubes, despite them all being milspec.

Or as the kids say these days, MiLsPeC

I bought 2 stocks at the same time, and one works great. I sent the loose fitting one back yesterday for replacement.
