Question: When used with the Brassstacker mount, can you still use Mosin 9130 Iron Sights with this one?
Document: The long eye relief is clear and measured it about 9 inches away. Didn't use the mount that came with it it fit but used a munt I made that goes above the rear ramp site, Can look under and use the iron sights or above and use the scope. Now I need to see how it handles the Mosin recoil.
This mount is two point, solid and allows you to keep the iron sights and use them. I have installed it and it works great. It is $60 but you pay for what you get.Brass Stacker MN9130SSM Nagant RiflesFor a scope I went with a long eye relief pistol scope that was on sale with free shipping.
I bought this scope last fall for my M91/30. Originally I was going to remove the rear sight and mount the scope as recommended. However my rear sight was soldered on, and I like having iron sights. So I made a homemade bolt on mount bracket to mount the scope. I punched out the two pins on the bottom of the factory rear sight, and the pin for the sight leaf. Then I made an angle bracket with 3 holes, one for each pin hole in the rear sight.
I have replaced the scope twice now. I did not bother with the mounting hardware that came with it. There is too much flexibility in it, like one guy said like mounting it to a diving board. I removed the original roller coaster iron site which left a 3/8 dove tail that you can mount directly to with a 3/8 set of scope rings. I used red Loctite on everything.
The scope seems to be a bargain. It appears to be good quality, and the price is definitely right. I did not use the rings or mount, since they aren't robust enough in my opinion. I used rings with four cap screws rather than the two screws on these. I also went with a different mount due to the reports of what happens with these mounts under recoil from the Mosin. The scope seems to be well worth the $50.
This scope is as described. I am using it on one of my Mosin Nagant rifles. It has no problem with the recoil and has kept its zero setting. The seller was quick to send the scope and gave an accurate description of the scope. I have no problems with dealing with this seller again, and will probably do so in the near future. I did not use the mount, or rings, since I had a Brass stacker mount and good weaver rings.
The mount keeps coming loose, making the whole setup useless. I decided to go back to using iron sights. For best results, you need to drill the receiver.
The Good:Not very expensiveScope is decently builtClear visualComes with lens coversComes with cleaning kitQuick shipping from sellerThe bad:No instructionsKind of hard to move the dialsI never used the mounting system since I read they are all garbage. I used the dovetail underneath the rear sights on the Mosin. Mine were welded on so I had to torch it, drill it, and hammer away for my life. I will test this scope out at the range pretty soon.
I shot about 80 rounds through my Mosin after mounting the rail and it didn't budge a bit. If install it as it is designed you will have no problems. Mine is solid as a rock. Make sure all the screws are tight and use thread lock, I used the medium thread lock and a laser bore sight to get it level and in the proper position.Don't be stupid and leave in the spring which is under the factory sight, it pulls right out using pliers.
This was definitely the easiest method of adding optics to a Mosin Nagant. I liked it, however after owning 2 over about 6 years, I have 2 complaints.First was that it was very difficult to keep from getting loose. I would have to re-tighten and re-sight after around 40 rounds. I later added some thread lock compound and it helped, but was still needing adjustments after a while.Second problem was that my first one actually sheared the main bolt due to recoil.
Answer: yes
