    B&C M40 adjustable butt plate

    I want to install an adjustable butt plate to get some more custom fit. Anyone ever install one? There doesn't seem to be any screws on the butt pad to allow its removal. Do I have to saw it off? If so where do I cut? On the pad portion? On the black plastic plate before the pad? Or on the stock before the plastic plate? Once its cut off will there be anything solid underneath to mount the new butt plate?

    If there are not two tiny little holes, the pad is glued on.
    If there are tiny holes, you grease a phillips screwdriver and slide it into each hole to access the hidden screws.
    There is a metal reinforcement plate molded into the pad within about 1/16" of the flat edge of the pad.

    On the glued-on ones, I slice through the pad with a bandsaw about 1/16" away from the stock.
    Then you can peel the last 1/16" of the pad off of the back of the stock.
    There is a little foam in the back, but you may need to fill it in to have something for your new pad to attach to.
    I have glued threaded inserts in there to attach a new recoil pad with a spacer system and machine screws.

        Found a thread on Sniper's Hide adapting the Tool-less adjustable butt pad accessory from the KRG Bravo onto a Tikka CTR stock. From what I see the Tikka's butt pad profile looks similar to my B&C M40. Would anyone know if they're about the same?

          How often does your length-of-pull change?
          I don't see any value in "quick adjust" hardware on rifle stocks other than to be able to quickly remove the cheekrest to be able to clean the barrel.
          Ant then, I want the cheekrest to only return back to where I removed it from.

            Based on your response I take it that you're not fond of these "tool-less" adjustments. Most likely because they're not reliable and can fall out of adjustment in the middle of shooting eh? For now I just need some additional LOP and will fix that with just a slip-on pad. I was exploring the idea of having an adjustable to add offset and cant in an effort to gain better fit.

              How come no one considers the adjustable buttplate that you can move up like the adjustable cheekrest. This keeps the butt in the shoulder pocket.

                  Thats exactly what I'm trying to achieve in this mod. The accessory I was originally trying to use was made for shotgun stocks.

                      Not sure if the Tubb 4-way is still available. It was reasonably priced from Midwayusa

                        It say its discontinued on both Midway and Brownell's site. Saw another on Ebay made by Graco. It looks workable but I would have to do some serious cutting or grinding to have it fit flush to the stock's plate profile.

                          Masterclass stocks have adjustable buttplates. They look similar to the Tubb style with an adapter plate.

                            You can look at buttplates meant for 3- or 4- position smallbore rifles as well. They tend to be kind of pricey though.
