Scope mount

The Burris PEPR mount gets alot of praise under the $100 mark. I had a Rock River Arms Hi-Rise mount that was solid as a rock though a bit heavy/bulky, cost about $60. I currently have the same Primary Arms mount you have but haven't shot it since switching the scope and mount.

I have $35 Weaver one piece mounts on a couple rifles and have had no problems with them.

What type of rifle will the scope be mounted on, bolt, AR, etc?

I’ve had good luck with the PEPR too.

Ask OpticsPlanet if they'll take it back. If they will, give the Atibal QR mount a go. If you're feeling up to something a touch more spendy, go with an ADM mount.

If they won't take it back, blue locktite that sucker.

This one? I just picked it up on sale a few weeks ago, heavy but extremely solid and easy as any other 1913 accessory to mount. It was solid through several hundred rounds of 5.56 at the range this weekend. Double check that it has clearance at the rear (closest to charging handle) where it attaches and loosen the bolts so it can hook the opposite side rail.

It’s darn near a copy of the Burris so unless you got a lemon example, it should be fine. I think you simply ran the bolts out (loosened) and instead of pushing them in after (toward opposite side) you left them in position such that the starboard side claw was too narrow to engage the opposite side rail. I think you’ll find you need the washers and a good amount of torque to keep it engaged but it shouldn’t move once set correctly.

One of my 4 daughters who also fired the rifle using that mount.

PEPR and SSALT are the same mount.

The AERO Mount is very good and very light. I have many mounts from Larue on down but for a non QD mount on an AR the AERO mount is very good .

you didn't say 1" or 30mm but the 30mm is about $75. Not they have extended and standard length of your needs. I use the extended for 1-8 Vortex on my pencil barreled carbine. Rock solid and as light as it gets.


Looks like the PA is a 30mm, so :

Maybe I missed it, but did you use a torque wrench when you mounted it on the rail initially - prior to it coming loose?

Is it possible they came loose because they weren't torqued to spec?

Mount. If you look at the above pics of the mount, you can see the "rings" are pushed forward on the mount. The cantilever design is just easier to mount optics to the rail space limited ar.
