Free: Contests & Raffles.
While I agree with what has been said, one thing to consider is the rubbers ability to grab or stick to things. Particularly your clothing. To me it would depend on the use of the rifle when it came to a hoque stock. If its going to be a brush gun by any means, where fast action may happen I would seriously look at how the rubber grabs on to your hunting gear when in those situations. I have one on a 10-22 and as advertised it fits well and does feel nice when in position but like I said it grabs every bit of clothing on the way to your shoulder.
