Tech Help With TA51 Mount

General General Discussion
1

Does anyone know what the proper thread pitch is for the TA51 mount thumb screws (used on ACOG)?

My intent is to replace the thumb screws with a proper nut and lock washer for my mount. If anyone has information on this or has done this before, I would greatly appreciate the info.

TIA

Do you have the mount already to count the TPI and bolt width? This will give you proper bolt size. Or take the screw to a hardware store and measure.

No.

But I can recommend you choose a nyloc nut over a lock washer.
