You might need to hose the adjusting holes with crud cutter/brake cleaner to get the oil off. Then just use the blue locktite. The red is for permanent locking. The blue will gum it up just fine.

Update
I would like to say thank-you I did what you all suggested and degrease the screw hole and the screw and I went to the range and fire off about 50 shots and the rear sight stayed tight.

Had the same problem with loose factory rear sights. will try the solutions that recommend the de-greasing the holes and screws.

Any time you use loc-tite or similar agent, it is very important that you de-grease the screws and screw hole threads. The oil on the screw threads acts like a release agent and the loc tite will not bond to the metal. For you guys that need a fast fix for this problem and do not have any loc-tite, use your wife's fingernail polish after de-greasing. It works very well also.

BTW, LocTite also makes a purple version, which I find works best with small screws like the rear sight screw.

General rule for LocTite:
Large bolts (like in an automobile): Red (You should never use red on a firearm.)
Standard screws: blue
Small screws: purple

And, as mentioned above, you must degrease both the screw and the receptacle before applying LocTite.

I'm new and this is from my first post, about Mini in 300 BLK. Saw jimkok's question/issue and his mention of Tech-Sights, so thought I'd jump in.

(A note about the less-than-satisfactory outings last summer ... there were never any issues with the rifle, per se. However, sometimes, groupipngs would be nice and even quite tight, very much like the 10/22, but with bigger holes. Other groups would start to open up. With that big barrel on the 300 BLK Mini, I didn't figure it was the "stringing" I've read about with some of the thinner-barrelled Mini's. It turns out that the rear sight would sometimes be "fixed" and sometimes liked to work itself loose. I chose to live with it for a while rather than LocTite it because I intended to put Tech-Sights on it as soon as they had 'em back in stock for the Mini.)

This I have done, and while I appreciated the left and right set-screws on the Tech-Sights product, I did use some LocTite. Worked like a champ during the one session I've had since I put it on, about 3 weeks ago. Had the gun out last night and it's still rock-solid.
