My wonderful wife bought me a Primary Arms Micro Dot MD-06L with the Seekins Precision Mount. The L means the on/off knob is on the left hand side of the optic.

My first impression was wow, this thing is light, and the red dot is easy to see and bright.

The 4 screws that hold the optic to the mount did not come with loctite.

The bolts that go through the rail do not have loctite on them either.

Should I add some loctite to the screws and bolts?

I always put a small dab of blue Loctite on base screws and ring screws. On my Microdot I Loctited the 4 screws and the screw that clamps the riser to the rail. Just make sure you use Blue so you can remove the screws down the road...

BTW, enjoy the Microdot. I have two of them and they are a great value. :thumb:

I have the same optic on my AR pistol and I did not see the need in adding loctite. It's sturdy and has not loosened, but I also have a QD mount on mine.

My rule of thumb is to use blue Loctite on any of the screws/nuts that may work loose. Just my 2 cents.

Always loctite all screws on optics. 90% of the time when a gun came through the shop because the scope wouldn't hold zero, it was in the mounting system somewhere, rather than the scope itself.

Same here.

I loctite any and all screws...on anything I'm working on.

Can't think of any occasion when a screw working loose would be a good thing. I use Blue, so you can crack them loose anytime.



Nice optic and mount Kev, let us know what kind of battery life you get...

I second the value of blue locktite on optics screws, and I always apply it anytime I reinstall any screw on a firearm. The more they are removed the less holding ability they retain.:thumb:

Shoot it First before putting any loctite on. Let the parts "settle in", then keep snugging them up until they are settled.

AFTER everything is properly seated and dimensionally stable, then loctite.

 

[madcritter]

Yep blue Lottie on all optic screws.

My stepfather taught me a trick using clear fingernail polish in replacement for locktite. Locks it down pretty good, but isn't such a pain to remove in case you have to remote the optic.

Sounds crazy, but it works pretty well.

I have used a dot of red fingernail polish on the threads for years, screw it down and wipe off the excess and the remaining ring of polish is a visual indicator if the screw ever starts to back out.

This is the part that gets me every time. I zero my optic, feel compelled to keep shooting, and don't Loctite it until I get home . . . at whick point I question whether it held zero or not.

Blue loctite. Be sure to clean the threads of any grease or oil first. Best way ive found is to apply a small bit to the threads with a toothpick.
As said previously you can use clear nail polish but it doesnt hold as well, but removal is easier after applying alittle nail polish remover.
Either way its a good way to minimize the chance of lossin your zero.

Better to have to tweak it next time out, than to have loctited something looser than it should have been.

Absolutely, My LaRue mounts all came with blue locktite installed. Remember to re apply if you remove and replace.

In electronics assembly we always use finger nail polish to do that, it is cheaper than lock tight.

All adjustable pots and freq's and many of the nuts and screws are locked in place with a small dab of finger nail polish on them during the assembly of them. Our electronics have golf balls hit off of them so they get a lot of shock during use. The fingernail polish holds up nicely within this use.

Finger nail polish is nice because it holds quite well but is still fairly easy to come back and break loose without too much force later on down the road in parts replacement and repairs.

Finger nail polish can be used in many of the places that one might use lock tight.

Blue Loctite may be okay for some but I have found more than once I had to either use a lot of heat to break screws loose or to drill them out after I rounded them off when using blue Loctite.

For several years now I use nothing but purple Loctite (222MS) on small screws and have never had any work themselves loose under recoil and the screws can always be removed, if needed be, with very little effort.

 

[mattmuttsmith]

You absolutely want to use blue loctite. You don't even have to use alot. Just one dot, spread it around the screw, and your done.

Good luck.

 

[John_Auberry]

I used to use blue locktite, but I tried purple and never went back.

 

[joes]

Always blue locktite never the red...
