Remington 870 Return To Zero Post Cleaning/Barrel Removal?

[DDTSGM]

It's a vang 870 with their plus two extension.

I am using a Magpul barrel clamp.

That could be what caused the point of impact shift. That actually makes sense. I torqued the clamp to the same spec but its' not oriented EXACTLY the same as it's impossible to put that back in the EXACT same spot every time.

Anyone think this is a valid theory?

The barrel is seated fully to the poster that mentioned it.

I think it is a valid theory.

Vang says their +2 is rigid enough to use w/o a barrel clamp. Maybe take the clamp off, remove barrel, reinstall and shot, then repeat to sif it holds POI. Then you will know. Then you will have a decision to make as to the clamp - I ass-u-me you're using it as a sling mount point.

Nailed it.

Sling point. Hrmph... lol.

I could go back to the vang/GG&G sling mount i've got for this shotgun and ditch the Magpul clamp.

I'll have to test all of this out eventually.

Shooting it with and without the clamp installed should tell the tale.

I'm sure that you are already aware that shooting slung up with a rigid sling can pull the barrel, too.

Yeppers.

No sling was being run when I was patterning post cleaning.

I'll run the gun without the clamp the next time I'm at the range and report back. It probably wont be until March.

Thanks for the help guys!
