AIM SPORTS M44/Mosin Nagant 91/30 Scope Mount (Short)

How To Properly Install This One: Aim Sports M44/Mosin Nagant 91/30 Scope Mount (Short)I guess it takes a little Physics to figure this one out.I purchased a pair of Nagant 91/30 rifles manufactured in 1939(Hex) and 1942(round) respectively and set about to mount a scope prior to converting them to sniper rifles.I decided to try this AIM short mount so as not to have to drill and tap the receiver. The material is so tough that Drilling and tapping these weapons REQUIRES solid carbide tooling.All the set screws come to points... and The first thing you need to do is REPLACE the front set screw with a Cup-type screw instead of one that comes to a point on the bottom.In a pinch, you can simply grind or file the point off of the existing set screw. This is IMPORTANT because that screw presses down on the front wall of the sight mount, which is rather thin and may be deformed by the original screw. ( You may want to take a flat riffler file and remove a bit from the top of this front wall and flatten it out ). Also, the folks at AIM really need to move that set screw hole about 0.050" toward the rear of the rail.... that would place the screw directly over the center of the bearing wall.After removing the Rear Iron Sight Ramp by tapping out the front retaining pin, you will want to remove and FLIP-OVER the simple bent-leaf spring so that the "hump" is in the middle and facing UP. This is also IMPORTANT because it alters the position of the FULCRUM which then redistributes the force triangle and stabilizes the open end of the rail.You will also want to run a drill through the threaded hole at the front of the rail and throw away the included mounting screw. Make sure the drill is the same diameter as the original PIN that held the iron sights in place.Place the barrel in a vise or use a screw-clamp to compress the new rail against the inverted spring until the drilled mounting hole lines up with the holes in the "Ears" of the sight mount.Tap the ORIGINAL PIN back in to hold the rail in position and then tighten the Front Set Screw until the rail is LEVEL.Tighten the remaining TWO set screws to set the rail in its final position.You will find that this general approach works for ALL of the following Nagant rails and provides a Rock-Solid Installation on ALL the 91/30 and M44 variants.ATI Mosin Nagant Scope Mount with Bolt HandleMosin Nagant Weaver Rail Type Scout Rifle Scope Mount For 91/30 M38 M44 M39UTG Mosin Nagant Tri-Rail MountMosin Nagant M44 M91/30 M39 M38 Rifle Scope Mount Short NEWBest regards,Offgridsid

It works, and it works great. As others have mentioned, it does NOT come with mounting instructions, but they are not needed. The reviews here on Amazon were superb for helping wrt installation of this scope mount onto a Mosin Nagant (almost better than the Nagant forums!). Mine is on a 1946 M44 Russian carbine with bayonet. The AIM scope mount does come with three allen wrenches. First, learn about your weapon (there's a TON out there about the Nagant). Here's a bit more detail for installing this mount CORRECTLY and with MINIMUM DRILLING/METALWORK: Punch the pin out of the rear sight pivot on the rifle, and remove the rear sight leaf. Leave the rear sight leaf SPRING (the FLAT, horizontal, metal piece) on the rifle. Take the thin mounting screw out of the scope mount you just bought. Drill out the hole in the scope mount that the screw was in (needs a 1/8" drill bit). Throw away the screw (and nut). Use the smallest allen wrench to loosen the hold-screws on the SIDE of the scope mount. Fully remove the FRONT-most set screw from the scope mount, using the largest allen wrench. File down the "pointed end" of that screw to "near-flat" using a normal metal file, and re-insert the screw into the front hole on the scope mount. Set the scope mount on top of the rifle's rear sight mount. It will NOT line up when you first place it there, and it will NOT line up with simple hand pressure! Use a C-clamp to compress the scope mount into position on the rear sight mount (use some rags or something to protect the rifle and the new scope mount where the c-clamp engages each). It WILL line up FULLY with a c-clamp! Tighten the c-clamp against the heavy pressure from the rear sight spring until the drilled-hole in the scope mount aligns with the rear sight mount's side holes (where you punched the pin out). This will take some torque! There is NO NEED to drill additional holes in either the scope mount or (heaven forbid!) the rifle! Once aligned, gently tap the pin back into the now-aligned holes, to hold the scope mount in the rear sight mount. (Right here, you can almost be done; the thing is in there rock-solid just from the spring pressure.) Loosen the c-clamp and move it aft a bit (~ two inches), towards the rear of the rifle, and tighten the clamp again to get "parallel alignment" with the barrel. Tighen down the front set screw on the scope mount (the one you filed down). Tighten the hold-screw on the side of the front set screw. Remove the C-clamp. For grins, go ahead and snug down the aft two set screws on the mount, and then the hold screws on the sides; regardless of what you do with those, this scope mount is NOT moving! It is held firmly in place, almost with just the pin and spring, without screws! Don't be dissuaded; for $9 this is GREAT, AND you do not need to make any "irreversible, permanent" changes/drillings into your relic weapon. You can always reverse the process and put your iron rear sight back on. Buy this with confidence. Also, concur with need for LER scope and a good ring set. Try these, they work great with this rifle/mount combination to get the proper eye relief (8-10") without breaking the bank:Leapers Accushot 1-Pc Offset Mount w/1 Rings, Weaver/Picatinny MountNcStar 2-7X32E Red Illuminated Pistol and Long Eye Relief/Ring/Blue LensEnjoy your weapon!UPDATE: Took this to the range. Worked perfectly. No problems with recoil; the mount held solid, scope was zeroed, everything went fine. Did not need loctite either! Buy and install this with confidence. Works like a charm. NOTE: you don't need the Leapers Offset mount. The offset would actually put the scope over the extraction port and possibly damage your scope when extracting the shells (as well, my Nagant is a straight bolt, so I could not open/close the bolt with the scope set back far). The mount rings that came with the NcStar scope worked fine. Save the few bucks there.

First, instructions are horrible. Spring beneath old sight must be rearranged. Mount still doesn't sit properly.Second, entire mount does not reliably align along barrel due to space between mount and site bracket.Third, adjustment screws completely knock mount out of any semblance of alignment with barrel.Fourth, when installed, mount is so far out of alignment it could never possibly be sighted in with scope adjustments.Fifth, all of this does not matter at all, because the entire assembly is so flimsy it would certainly be knocked out of alignment after the first firing (if you could actually achieve that in the first place). In fact, slight thumb pressure anywhere on this mount easily misaligns the entire mount at any time.Albeit this thing was inexpensive, it still wasn't worth a dime and certainly not worth the time I spent attempting to get it to work...
