It do annoy me many guns are designed like this and so necessitate solutions like this, or aftermarket chassis like the K&L one for my maverick
There should be a proper bipod mounting location, or sling mount on every gun, this idea with a little rail just in front of the trigger, that i feel is a bit like pulling the leg on people.
As a result i have ditched the bottle / tube clamps i have been using, and gotten a caldwell BR support i can rest and fix the bottle / tube in, this way at least when the gun are not in use it dont look stupid.
Even if i as a Dane, and for us not atypical, to have function over form,,,,, hence the term "Danish design" for really understated design, then here i must insist on not needing to strap on too many aftermarket parts, not lease when it should not really be needed in the first place.
