Will this fit a Diana Chaser rifle?
Yes. The Chaser has a weaver base on the barrel band.
Will this fit on the Hatsan Flashpup?
Will this bipod work on Hatsan 95?
Will this fit on a Crosman MTR77 NP Scoped Air Rifle.
No but a clamp-on could work ?
will this bipod fit on the hatsan 125 sniper rifle & what do i use to mount it on with
Will not work on the sniper 125.
Will this fit my Hatsan AT44-10 QE Short?
Yes as long as it has a weaver rail. My AT44 Hatsan QE Long does.
Will this work on the talonP?
UTG11mm to weaver UTG 11mm-to-Weaver Adapter, Vertical Scope....
Yes you would need a dovetail to picatinny/ weaver adaptor mount either by airforce or UTG. My talon-p has a one piece stock made by maddog so i installed a swing swivel stud under the forearm. Then i bought a caldwell XLA bipod 6" to 9" inch model at big 5.
would this fit the Benjamin marauder?
Provided your m-rod swing swivel stud installed in the forearm , then yes. Then there are adapters made for this application.
will this fit well on my Diana Model 48? Good choice or?
I would install a sling swivel stud and then purchase a caldwell XLA bipod then it will mount directly to the sling stud. Its up to you the bipod is at least twice the price of this one. Food for thought. Also springers don't do real good with bipods but very good with PCPs.
Will the bipod clamp to the barrel of my hatsan 125 sniper? And if so does it effect accuracy shooting with weight of gun resting on barrel with bipod vs. you sighting in on sandbags? Always wondered if it would make difference.
This is not a barrel clamping bipod. But normally for barrel mounted bipods we do see changes in point of impact and accuracy with and without one.
