I'm looking to install a Picatinny rail on the underneath side of my new Marlin XT-22RZ (a bolt action, threaded barrel .22LR). It has a polymer {plastic} stock. The Picatinny rail will be used to attach a bipod. The fore arm is pretty much hollow space - it does have some 'molded in' bulkheads ever couple of inches down the length of the fore arm and a rib/bulkhead that runs lengthwise down the bottom of the fore arm channel.
The long rib is centered in the middle of the fore arm channel and maybe 1/16" thick. And of course that's exactly where I will be drilling the two holes to mount the Rail (fore & aft). So, between the perpendicular supporting bulkheads and this long one running down the middle of the channel, I'm left with, what basically are four little compartments or chambers that I'm looking to put some kind of "filler" material in.
So....finally, my question: The filler material needs to harden and be able to be drilled through (to support the mounting bolts of the Picatinney rail). What type of resin can/should be used for this? (I'm looking for name brands and/or where to buy it).
I'm sure gun smithing folks run into this often - but I'm fairly new at having to try something like this. [Also: the Marlin molded swivel shape makes a bipod swivel mount unusable, just in case you were about to suggest that path]. Any suggestions will be much appreciated!
