It's the port where they purge and nitrogen or argon fill the scope. Leave it be.
Every time the rifle is fired, it clicks the rounds fired clawk inside the scope.
Usually it's on the bawttum right side.
Twisting thuh nawb will locate it in either corner.
Push it in to reset the counter.
Great feature..............................![]()
Looks to me to be the 4.5-18x40 Bushnel AR Optic, which I just bought. But I could be wrong.Can anyone tell me what the heck this little cylinder is, at the bottom of my scope, that sticks out at a 45 degree angle?
Thanks

ps: this is on an inexpensive Bushnell 6-18x40 Rimfire scope

You are probably right, I just grabbed an image using Google, rather than taking a photo of my scope. The reason I was asking is that I just purchased a very inexpensive Bushnell 6-18x40 scope and this projecting "gas port" is causing a slight clearance problem with my rail. THe "gas port" is causing my scope to be canted about 2 degrees. The rail and barrel that it is attached to, are much more expensive than the scope, and I don't want to replace my Warne QD rings with a higher set, so I was hoping I could file about 1mm off of the bottom edge of the "gas port".

Looks like we have almost the same set up but I used a Mueller 4.5x14AO, deadly on the pests.
Alter the base to clear the projection.
would look alot nicer if if it was flush with the bottom .
I believe that is the Burris posi lock. Once the scope is sighted in it supposedly locks that setting until the posi lock is loosened.
The scope comes with a special tool for the locking system.
