Due to many confusions I am requesting a sticky on this matter.
The Burris Fastfire II can be bought in two configurations:
1. Picatinny/weaver Base.($209.00 Cabelas)
2. "No Mount"($199.00 Cheaper than Dirt)
The picatinny/weaver has an extra part that allows the sight to be attached to any weaver/picatinny base like a regular scope.
If you want your sight as low and as light as possible you can use a ''marlin 336 bases" made for the fastfire.
This bases was designed specifically to mount the "No Mount" sight on a Marlin 336 rifle.($47.00 Gunbroker)
It has been adapted to be used on flat top receiver of shotguns like the Remington 1100,1187 and 870, the Mossberg 835,935,535 and Browning BPS and Gold. It requires two 8-40 thread holes in the receiver 1/2'' apart.
These are very common configuration and found on many predrilled receivers.
Use of the Marlin base replaces both the Weaver/picatinny part included in the first package and the weaver or picatinny base that is on the gun or provided by you.
I am sure the sight can also be mounted on many other flat top shotguns.
The Protector from Gobbler74 can be used with the Marlin bases. He includes slightly longer screws to accommodate the thickness of the protector.
Are the marlin bases 1/2 in center to center? also are the 8-40 screws the standard or are there different thread patterns? thanks
Thank you paladin. I was wondering if the marlin base would fit a factory drilled/tapped 870, now I know. Wanted to get the sight as low as possible.
i think the 870 drilled at factory use 6-48 screw.
My 870 and 1100 were not factory drilled. If it is 6-48 you could look for new screws or drill to the 8-40.
Yes 1/2" center to center, but if you are drilling get the base first.
I have a weaver rail for the 870. Can the screws for it be used to secure the marlin mount to the reciever of the 870.
Will the Marlin mount work on a Winchester SX3?
