Picked up a bargain ($25.00) Mosin-Nagant 91/59 that in the past had been somewhat sporterized, (UGH) but has proven to be very accurate with cast bullets. As it was already approximately the right size, decided to scout scope it.

I viewed Junior Doughty's page on installing one of the cheap scout scope mounts on a Mosin-Nagant and learned much.

I took a similar, but somewhat different approach for one of the $15.00 aluminum Weaver style mounts from http://www.htownimports.com/ (BTW, Zack, from Htown imports was great, when I enquired if he had rings for sale, he said no, but then threw in a set for free)

As Junior pointed out, the scope mount comes drilled and tapped for little socket head screws to be installed in holes for rear sight pivot/retainer pin. But also as he made clear, this set up leaves a bit to be desired, as under recoil forces, it has a proclivity to rise up in the rear, and pivot down forward.

I drilled and tapped the front of the mount for 1/4 x28 bolt (and for a 6-32 locking set screw) and drilled out end of bolt for a turned down shank, press fit brass button, installed the OEM mount screws and squared the mount parallel with the bore. With all tightened in place and aligned, set up on mini mill table and drilled through and through the sight side plates and mount base. Removed mount, drilled out 5/32" clearance holes in side plates and then tapped mount base through from one side for 6-32 socket head screws, installed mount, took and zeroed, accurate, scope very secure and immune to recoil.

As I had some scrap leather and hard dense foam rubber, made up a riser cheek piece.

I left the front sight and hood in place, as have a Weaver mount rear aperture sight on order, I will zero it, then remove. If the EER scope should malfunction, can remove it and then re-install the aperture sight.

With the above screed aside, pics are worth a thousand words.

This is a scout I made up years ago from a $90.00 buy. Is a FN 98 Mauser that had been rebarreled to 7.62 NATO by the Israelis back in the 1960s, the bore was/is like new, as it has been cast bullet fed. I cut the barrel down to 18.5," fitted wood from forearm to make up raised cheek piece and installed a Timney trigger. Retrofitted a B-Square mount for a more secure unit, in case the scope should fail, made up a ghost ring rear aperture sight and a front sight at forward end of mount. I shortened butt stock by 1," cut the cup butt plate off to near flush and refitted, also drilled out two holes in butt stock to lessen weight and epoxied in 1/2" thin wall PVC pipe to retain integrity. Milled out bolt knb for a bit of weight reduction.

This is poor boy ghost ring aperture sight. The square stock is 3/8", the round (with flats) is 1/4". I drilled and pinned 1/4" round in the upper 3/8" square, hard silver soldered, milled flats, then graduated. With the locking set screws, the flats prevent the adjustable components from rotating, the ghost ring is drilled and tapped for different sized apertures if so desired. Receiver was drilled and tapped 8-32, bottom 3/8" square stock attached, then fitted to wood. Camera angle in second pic makes things appear misaligned, but they aren't.

Retrofitted B-Square mount, the OEM drilled and tapped hole in middle of mount was where it was originally attached at sight ears. For retro, I reversed the mount and slotted to lower with a tight fit, drilled and tapped through for 8-32, the raised portion at rear of sight base was also drilled and tapped 8-32 and rear of mount is locked down there. Front sight I installed can be seen at front of mount, it clears top of mount enough to give a good sight picture with ghost ring.
