Hey guys and girls, quick question. I have recently installed a Monstrum Tactical (lower end company) scope on my hipoint 4095 carbine and I am having issues. It seems that every 20 to 30 rounds I put down the tube the scope moves forward because of recoil. It is highly annoying. Does anyone have a fix for this? Locktite has failed me as we'll :/
 
I had the same issue where glue or tape wouldn't do the trick. Took it all apart and checked only to find out that the rings were a hair oversize for the scope. They were both listed as being the same size but somehow the manufacturer tolerances went in the opposite ways and I had a gap. In my case the cure was a full ring shim of pop can side metal to fill in the difference.

So take off the top saddles and see if the scope moves a little side to side. If you can see ANYTHING then you've got the same issue I had.

Rubber cement or contact cement is considered excellent for securing the scope. If you need a shim then cement both sides of the shim.

Or, of course, just get new rings that actually fit the scope.
 
Is your carbine fitted with the original plastic Weaver rail or did you upgrade it to a metal Picatinny rail?
 
ohhhh.... hmm yeah I will keep that in mind. But for the time being, do you have any other ideas on how I should cope with the plastic rails? I am stumped..
 
consider using irons until you can afford a better optic. If money is tight it's not worth spending $20 on glue and gadgets when hopefully in a few months or maybe a year you can fix it right.
 
Come on, guys. Here is the thing. I am 18, I work a fast food job from hell and about 90 percent of what I make I am putting towards going to college this fall. The other portion I use to make payments on my car. Therefore, I have very little to put towards my three guns. The scope I bought was from an amazon.com gift card I received for Christmas. It isn't the best but I take what I can get, okay? Oh, and I have really only been in the firearm community since the summer of 2011 (about when I joined this site) so while my name implies that I would like to be a gunsmith someday, I am not there just yet. Although I could practically disassemble my mark III in my sleep, which is no small feat as any owner of that pistol would know.... I have learned much, but there is still more room to grow.

Anyhow. Pictures and a link....

My photos aren't the best, I know. They are the only ones I currently have on my computer. Thank you to all of you who are helping me out.

OK, I can't really see the mounts on your carbine in those pix. The amazon pix seem to show the scope on a picatinny rail. There are two screws in your scope mount that need to line up with slots in the scope base. A Weaver base usually has only two such slots and if they are not spaced the same as your mount, there is your problem.

You have 3 choices.
1. Get a picatinny rail
2. Get a file and cut the necessary slots in the Weaver rail.
3. Put the scope on the shelf until you can do #1.

I really suggest 1 or 3, but 2 will give you some gunsmithing practice.

Of course, I may be totally off base because I really can't see much detail in your pix.
 
I think you will be fine if you just change the rail on the gun. Be sure to get a metal Picatinny rail.
 
Interesting, they changed the design. My HiPoint had a metal rail.

Call Beemiller (HiPoint) and tell them your situation. They may have a metal one they can send for free.
 
sometimes, things can be solved using double-side adhesive tape, the type used to fix mirrors on walls.

I used them on several occasions between scope and rings.
 
It appears that the scope base cross screws don't pass through the slots in the mounted rail (they are higher than the top of the rail).

Perhaps you can take a small piece of aluminum that fits in one of the rail cross slots (0.200" IIRC for 1913 spec) and cut it into a rectangle that allows the piece to be installed in front of one of the cross screws.

I would guess the part would look like a B27 target shape (the head part protrudes up into the scope base to contact the front side of the cross screw).

Clearly, this is NOT a good reliable solution, but could be done with a scrap of aluminum, a hack saw and file.

BTW, gunsmiths and machinists learn how to use a file and a broom early on....so I figure this is a valid part of the process..

Being a gunsmith would be a great career and wish you luck in that pursuit.
 
After disassembly, degrease rings and scope carefully with rubbing alcohol. apply rubber(contact) cement. Wait until 'tacky", reassemble. fixed.
 
Hey, thanks a ton, guys. I will look into all of your suggestions and Try to get some better pictures uploaded as well.
 
He guys, I found a fix for my problem. I got a small rail mount and put in front of the scope mount. It is the part with the price tag on it lol. Just for closure, here are some pics.
