Threads on the bolt/thumb screw or the receiver threads?

I have a Gen 4 aluminum mount on my Loaded. Blue Loc-Tite is a requirement, not just a good suggestion. It will shoot loose if you don't Loc-Tite it. I was of the mindset that if you torque it good enough, it'll stay. Wrong.

welcome to the forum
Get yourself a Redneck Yankee mount. Do some minor DYI, get a rock solid custom fit and save beaucoup bux.

Are you sure the bolts are supposed to strip before the threads of the receiver. I have read a few posts here awhile back about the threads on the receiver and the fix for it. Do a search

Thanks from wildcat

Bolts are softer than the receiver

That might depend on what Bolt was used . Was it a Factory replacement Bolt or did some one replace it with an off the shelf one at some point . Ya never know .

AFAIK they're all purposely made softer so if threads get crossed it's the bolt that's damaged, not the receiver.

For those who inquired about the AWC I finally got around to listing it over on GB. Thanks for all the great history and info you have posted about it here I always enjoy learning the history on the old war horses.

I just looked at your GB listing; your item is doing well.

By looking at the serial # stamped on the mount, my guess is that it was originally mated with an M1C Garand. These were originally blued, and was reparked when put back into service. The right Garand collector would jump all over this.

Good luck with your sell.

Scope mount advice

Earlier this year I picked up my first M1A. With my new M1 I also picked up a SA gen 4 scope mount. I dont know what I was thinking....

When I went to install the scope mount, I found these monster, ugly as sin, mount screws that stuck way off the side of my M1A.
Being the mechanic that I am, I went down to my local true value and matched the threads to the closest length of 1/4 28 bolts I could find. I preceded to machine down the windage adjustment screw to propor length as well as my newly aquired replacement hardware. I sanded off all the grade 8 marks and also the zinc coating(knowing that the bluing wont take to well with zinc). I dipped my bolt heads in 44/40 to make them purdy and started to put the sucker together...
To my dismay... when I went to install the main mount screw on the side of the receiver, I gasped in horror as I found out that my beautiful 1/4 28 was not the correct bolt. I shook my head in shame as I found my bulbus stock mount screw and compared it to my formally zinc plated mini masterpiece.
Anyway, long story short. Searched the countrys bolt suppliers for what turned out to be a #12-32 sized bolt in gr8 but to no avail. Tried out a few different scope mount manufactures mount bolts but they turned out to be cheap mild steel, composition when I went to turn them down a bit.

Sorry for the long post but I've got a few questions still. First is, am I crazy for wanting and using gr8 and getting rid of the old hardware? Second is, does anyone know of a supplier of a high grade bolt in this thread pitch or even a die so I can make my own? Third is, was it a good idea to machine down the windage adjustment? Last question, does anyone have any good ideas how I can remove the Springfield Armory logo off the side of this mount (its ugly).

Thanks Gentlemen
