Older Scope mount help!

[clifish]

I'm wondering if a heat gun will get the area hot enough if left on for a while...

would probably not be enough and it will heat up too large of an area.

It should, if not, a small butane or propane torch will do the trick.
Wrap the barrel in a damp rag, and try to concentrate the heat as close as you can to the screws.

Dude sorry to hear about an accident!!! The 100 deadliest days this year have been bad!!! Crashes have been WAY up!

Oh and as others said, penetrating oil, I’d do a full week of a drop or two multiple times a day, then a proper gun smith flat blade is a must…..then get a micro pen butane torch and heat a few cycles, the screw as noted above…..and yes use a wet towel over the barrel or receiver then try, if no go apply pen oil over night then heat and try again……

I had a stuck steering shaft that I did this and after 10 days it just popped off……

PS you can use the torch in the kitchen for all kinds of things if you don’t have one yet

If you read the bottles of Loctite the various colors are thread diameter specific.
The thick stuff doesn't doesn't wick into the smaller threads.
Blue stops at 1/4" fasteners. Purple is for smaller than 1/4". Not sure the 2 different reds diameter.

Hey all, just going to say prior to my question… I am not sure at times if I am acting like my usual self due to a car accident I was involved in last Wed night. So, my apologies if I am not myself. The effects are really starting to set in.

Have a 308 that my son inherited from his late Grandpa on my wife’s side. Very nice one.

It had an older scope on it and I think maybe LocTite or something similar was used on the scope mount screws. They are not budging… not rusted or anything… just not turning at all.

Anyone maybe have a suggestion for a method on getting these removed?

Thanks for any advice.

I hope you get to feeling like yourself soon!

As for the scope mounts. What types of screw heads are they? My guess is flathead.

I think that guys have good info about trying to tight a little and then loosen.
After that heating it up and trying is your best bet.

If none of that works then off to the drill press with a smaller bit and maybe you can wedge a small sacrificial torx or hex into a bit of a hole drlled into the screw and work it.
After that is a full drill out with a small drill bit and then increase the drill bit until you can pick all the pieces out or get another screw started and drive the old pieces down and out the bottom of the hole, if the hole is drilled all the way through the receiver, if not then picking it out is your hope.

If all of that fails, I think maybe a thread chaser tap matching the screw threading.

Finally, I think people may drill the whole thing out. Fill with steel epoxy and then retap.

Once it gets to drilling on the screw things seem to get way worse in my mind. I think of things like "what if they silver soldered it in place" ugh lol.

Let us know where you land and may it be as simple as heating and unscrewing :D

If the head trips out or breaks I would try these before a full drill out…. These are money makers!

If the heat doesn't work, but it should, I'd personally take it to a Gunsmith before attempting any drilling and tapping. I can't image it costing over $40, which is what most Smith's around here charge per hour. Bring the Smith a bottle of decent wine, whisky, or a 12 PK of good beer, and it will probably cost you a lot less, if not free.

I'm very well versed with drilling, extracting and tapping, and I still wouldn't feel comfortable, drilling on someone else's weapon.

If you don't care about the old rings, go to if, you can hog out the old screws pretty easily.


For new Ring's, I highly recommend "Talley Rings & Bases" and a Wheeler lapping and aligning kit, or have the rings lapped, and scope mounted by a Smith. If you're not comfortable doing the work, you could buy the rings and bases and take the weapon to a Smith to have him remove and remount the scope, but make sure you tell him that you want the rings lapped, which basically mates the rings to the scope with 100% contact, so the scope stays where it's put.

Let us know how things turn out.

Good luck.
Dan.

Quick tangent on rings.

forktender I've run across this DiscoveryOpt brand of rings and was blown away with them for quality and then blown away again with their price:

https://www.amazon.com/dp/B0CMC8J2NN?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_3&th=1

Haven't had to lap rings with these (yep I have a ring lapping kit).

These things are awesome, they are super well machined. They offer 2 different types of aluminum (lighter than steel). They use the SAME screw for ring tops and bases so no needing to switch bits. They are sturdy as hell. I get the ones with an indexing tab so that the ring tops fasten down evenly vs one side more than the other.
The price is out of this world good when others are charging 3x for half the quality and need for lapping.
Everyone I tell that buys a pair is like "holy crap these are great"!

I've begun the journey of switching to these rings on all my serious rifles.
I know it sounds silly and that there is the "rings are rings" but these changed my mind completely and I'm glad to have found them so I figured I would share the info since we are on the subject.

If you do a search of Loctite Blue, Red, and Green melting temperatures it will give you the results in degrees. There's not a lot of difference.
