I have read to use 222 purple for the mounting screws. Would this cause any issues? I do not want this mount to be removed. What is a good thread locker to use if you want it solid. This particular mount tends to get loose after 20 rounds or so. Recently I over torqued the front screw and stripped it. The D&T threads are fine luckily.

An other question regarding keeping the bases solid. Is there such thing as an adhesive that can be used to help solidify the mating of the receiver and base.

Thanks
 
I use the blue loctite sometimes, only on screws that have come loose over time. If they stay tight on their own I don't use any type of threadlocker.
 
I use blue Loctite (aka Guntite), it's speced as removable. It also avoids the issue of corrosion making the screws harder to remove later.

There are many tougher grades of Loctite, I would avoid them for mounts or rings unless you intend to heat up the joints for disassembly later.
They are all called "permanent' grades for a reason.
 
You can bed a mount onto a receiver in the same way you bed a receiver into a stock. Metal-fulled epoxy for the mount, release agent for the receiver.
Release agent for the screws for the bedding.
That makes a better contact between the two parts.
 
in over 20 years I never had to use any heat to take appart screws of any size in red locktite but I have seen lots broke by corosion if nothing was used
red is stronger, but a rifle is not a jack hammer and blue is more than enough
the most important part is to make sure old locktite have been cleaned before to put things back togetter. if not done, threads can be dammaged

the green is not a thread locker but a bearing-sleeve retainer

Is the gun a heavy recoil?

Yup. It's a Yugoslav capture K98 with Zrak mounts. I have been shooting some hot S&B ammo through it. The design issue with these swivel mounts is that most of the shock is absorbed through the front mount. The rear mount is has the ability to move fore and aft creating more stress on the front mount.

I will try the blue me thinks, easier to find too. As for bedding the mount... I will have to get a gunsmith to do that.

The reason I asked about an adhesive is because I have read that most of the Bosnian snipers had some sort of epoxy residue on the receiver.

I want to get it as solid as possible without welding it.

I've only used Blue when necessary on pistol /rifle ..have the Red but have only used it on heavier applications like cars etc..

Try the blue, it will most likely work for you, if not try the red, but I'd go very sparingly with it.
 
Use a tab of hot glue between rings and mounts or some sort of two component glue.
On screws if you must use Teflon tape.
 
I like blue for the little stuff. If you do use red, you can heat the screw head with a soldering iron and it will come out real easy. The ones that are like glue sticks are nice, not as messy to use.
