Mosin Nagant Rubber Butt Plate

Product name: NM-MPLATE
 
Made of a hard TPU material, this butt-plate replacement increases shoulder-grip and reduces some of the felt recoil. You can also now stand your rifle up in a corner without it falling on the floor, my personal favourite feature.
 
Fits on any Mosin Nagant, though it should be noted that fitment may not be 100% perfect due to small variances on the buttplate of each individual Mosin.
