Saddle Adjustable Comb

Anyone have any experience with a Karsten adjustable comb?
Or with another type of adjustable comb that can be added to one of the factory stocks?

Have THREE which work VERY WELL

Also have several... definitely a better buy in my opinion than the Defensive Edge units. Thicker/heavier material, more solid hardware, and cheaper to boot.

Karsten stands behind them for any breakage.

The one known to have been broken was caught between an armored fighting vehicles body and its 800 pound door, he still replaced it.

I was just getting ready to ask, how in the world could you break one. I have one on two different rifles. They can be custom molded to your stock by placing it in boiling water. Heck of a product.

Thanks guys I think I'm going to buy a 6.5 x 284 barrel for my LA rifle later this summer.
I'll find a LA stock to put the Karsten on and perhaps a bipod....
