benjamin Gunnar Butt Stock issue

I put strips of tape on the tube and it helped, though there is still a bit of wiggle. If you buy a new stock, you'll probably need a new buffer tube because the factory tubes are not mil-spec diameter, they are closer to the commercial tube diameter. I really don't know if man companies make commercial stocks any more, but it used to be a thing.
The gunner is mil-spec. Along with the Armada.

I know Benjamin markets them as such, but my Gunnar's tube measures fatter than mil spec, and thinner than a commercial spec. This was a gun I picked up directly from Benjamin in December. Maybe Reximex had different suppliers for different runs.

The military spec receiver extension (commonly referred to as buffer tube) diameter for an M4 service rifle is 1.149" +0.000/-0.006 (from a Picatinny Arsenal drawing I got a hold of). Also, the threads on the mil spec extension are proud of the tube. My tube measured at 1.163" and the threads are cut from the tube, and I couldn't get any of my mil spec stocks to slide on (I use Bravo Company USA stocks).

I really wish airgun manufactures were more careful when calling things "mil spec" and instead call them "military style."

You’re just dealing with Turkish quality control because all the tubes on the Gunnar’s here are .140-.142 . If this was an issue when you bought the gun, there is warranty but your gun doesn’t represent every gun out there either. You’d be amazed at how many Turkish guns were actually stopped and held back at Crosman for warranty. I hate how loose it is as well trust me but the fix is always get a mag-pul. Hell even the Amazon knock off works better and tighter. Turkish quality control is part reason why we let them go.

Not to mention there are multiple ex marines up at Crosman that demand mil-spec.
