'Filler' screws for the BLR barrell.

[BigDaddyB]

Does anyone know what size screw the sight holes on a BLR take?

I've had a scope mounted to my pistol-grip, 7mmRemMag BLR and want to remove the sights and put in 'plug screws' to protect the threads.  I don't know what size to ask for and my Browning dealer didn't have the right size.

Thanks,

BigDaddy, I own 9 blrs at the moment and have never found the size to fit the rear sight screw hole. Maybe if you take the screw to a gunsmith he could match it up. Where I live that option is not available to me. If you find out i'd like to know also. Regards, Byron

Most guns use 6-48. The next most common size is 8-40. Almost certainly it will be one or the other as nothing else is used as a general rule.

Graybeard, The filler screws from the scope base holes won't fit. Too big. Byron

Those two sizes are "almost" universal in sight attachment and scope base attachment. So if one won't fit being too big that one is most likely 8-40 and the other 6-48. Now there is a remote possibility of it being another size but in guns those two are darn near universal.
