works only with the pri aluminum rings not the steel rings.

Written on Feb 08, 2023

My aluminum ones stripped out at 15in# and this will not work as a top cap for the steel rings.
I still havnt got a response from pri about this and I really like their stuff but this with the aluminum rings really annoyed me.

screw holes can be cut wrong to where they rip the threads out.

Written on Feb 08, 2023

When torquing one screw just went I got nothing to grab and the threads fell out of bottom of the hole.
The steel rings cant be used with the mini red dot base because the screws are different and spaced different.

Hands down the best BUIS I have ever handled.

I own many of these and never had a single issue mounting them or them ever falling off.
They are stiff at first to deploy but they eventually loosen up a bit but still stay locked in up and down positions.

If you smash your upper in a barricade yes they will lower but thats good because then they wont snap off like locking up and down buis out there.

They are also the most low profile buis I have ever encountered, which if you get the wrong height rings for a scope you shouldnt have an issue unless you try to fit a 50mm scope when you needed 1.7+ height mounts.

If you pl on suppressing this look elsewhere.

I havnt even shot this yet but there is no way you can fit any suppressor on this upper without changing the handguard.
Ballistic Advantage makes a 12" handguard using the atlas barrel nut but I dont know if their 12" handguard is short enough to fit for a yhm turbo mount.

This 12.5" inch handguard it comes with would be good for a 13.7 build so maybe if I find a 13.7 with atlas barrel nut I can not have spare party lying around all the time.

Purchased these elsewhere but they are very solid and the options to make them ambi 45* is great. I will be purchasing another for my next build.

griffin armament is a good company to deal with and I will be supporting them more in the future.
