Comb raiser with cheek adjuster for 870, or ?

[sjcslk]

After messing with shims i think i've discovered what my real problem is with this older Wingmaster. It seems that when i mount the gun, i'm somtimes looking over the other side of the stock. I think its because i have a longer neck. I wrapped a piece of foam around it which raised the comb, and when the foam also stopped my cheek i was now looking straight down the barrel. Recommendations (other than wrapping foam around it)? Thanks.

Possibly replace the rear stock with an 870 TB stock. TB model is the trap version and has a higher comb.

a morgen adjustable pad will help.

Does anyone have any experience with Beartooth comb raising kit 2.0? Its like a sleeve that fits over the stock and inserts raise the comb.
