Do i have to get a riser mount if i wanted to put it on the dpms, should i get an adapter
If you want it to co witness with the iron sights, yes a small riser would be needed.
How do you turn power off without taking battery out?
You turn the rheostat to the off position
What kind of adapter does Pyramyd Air sell that will fit the Beeman P17 to accomadate this optic?
Will this optic fit the Beeman P17
Not without some sort of adapter
Will this fit on my crosman 1377
Not without some kind of mounting adapter
Will this fit on the SIG sauer mcx co2 rifle?
What adapter would be best for a Crosman 2240 with a long steel breech for use with this sight?
A UTG 11mm to weaver mount .
will this work on a Benjamin Trail NP Air Pistol. and does this turn off by it self.
I wouldn't use it on anything that has recoil .
will this fit Crosman R71, 6mm?
Will fit directly on my Crosman Pumpmaster Classic (.177) without the "adapter".
No, it would not as it is a weaver type base and that model air gun is 11mm dovetail.
Will this sight fit a Benjamin Titan GP .22? What are other open reflex sights available for the Titan GP?
You will need to buy an adapter rail. I have communicated directly with centerpoint optics and this is one of two of their reflex sights they recommended for a break barrel rifle. It is machine gun rated and fully automatic tested.
No, it will not. I would not suggest using a sight like this on a break barrel rifle
will this sight fit a h&k mp5
Only if you buy a ASG Metal Accessory Mount Base... with it.
