I had problem with my groups moving around five shots here and five shots there in succession and fought with this for several days. Until I grabbed the ocular fast focus eyepiece and noticed it was loose. Cheap UTG compact tactical scope. When I looked through the scope and wiggled the fast focus eyepiece the reticle moved with it. I was about to toss the $140 scope when I remembered how the scopes of yesteryear had a threaded ring that tightened down on the eyepiece once you had it adjusted correctly. So, I stuck an o-ring and the appropriate length of piece of plastic, for my individual focus, between the ocular and rear bell assembly on the scope and tightened it down. Ah, that is better no more movement and no more wandering groups!
Well I recently picked up an LCS SK-19 in .22 so pulled my old Falcon Menace scope out of the retirement drawer checked and found the same problem a loose fast focus eyepiece so I understood why I retired it. Looking around for some repair parts I found an unused 1 1/2 inch kitchen drain washer and an o-ring just sitting around waiting for some purpose in life. I stretched the o-ring over the ocular and rolled it into place then slid the split drain washer into place. I then screwed in the fast focus eyepiece until it butted up against the drain washer snugly. No more play in the eyepiece and no more wandering groups and I saved myself from having to replace the $400 scope as well. Such an easy but permanent repair. The only negative with the repair is that the scope is now focused for my eye only.
Almost fergot my Hawke scope in the retirement drawer also with fast focus problems. Looks like I have already done the repairs to it.
I really hate the fast focus thing to me it is just a marketing ploy to give us an inferior product and make us think it is superior cuz it's a new idea. When acually it is cheaper because there is one less part to be made and machined. They could fix it by simply putting a spring inside the rear bell to hold things tight or give us the threaded ring back. When scope shopping last I picked up a Leopold for $1000 and before my purchase I made sure it had the locking ring on it so I would not have this problem again.
