Reviews & Ratings for Hi-Lux Optics Ruger M-77 All Steel Long & Short Action 1 Piece Picatinny Bases — 9 reviews — Page 1

Tried the product and was never to get a good fit. Talk to factory expert and made additional modifications. The unit still had alignment problems. Even after sending to the factory the the unit was not repairable. The alignment issue were not related to Optic Planet. I had to find another product for deer season.

I installed picatinny rail designed for ruger M77 bolt action , whoever were the machinist should be ashamed of themselves.
You can tell right off the bat my scope was way off from side to side, and up and down. I would max my scope adjustments to the max and still not get there, so I myself had to grind machine and fabricate myself. Never ever buy this product they do not I feel, retest and check on a M77 ruger.

The mounting appeared simple and straight forward. Mounting it the first time I noticed that there was a cant on the rear base that I was not able to shim out to keep the base flat. It seems that the rear tightening screw will move it where it wants to go.

Talked to the factory service department and recommended mounting the bases separately and grinding the rear mount to get it to lay flay. I am not able to get it to lay flat. Presently, I have shimmed the rear base to .060 in order to eliminate the gap below the rear base.

This is all before adjusting the zero. I have attempted to center the windadge to the middle of scope adjustment. It seems that the 0.060 starts me out with a disadvantage.

My original objective was to create more clearance between the bolt handle and scope for a Ruger M77 left hand. I was using the max dimension factory mounts and hands will not clear the scope/rings.

I will more than likely return it to the factory for them to check dimensions.

Overall it'll do the job. Installation wasn't difficult but it got a bit tedious. First problem, the way the windage adjustment feature is setup makes for a difficult time squaring the rail to the barrel. Too many moving parts so getting that perfect alignment and tightening the bases was a tad bit of a struggle. Machining is not perfect and Blythe time I had set up my rail straight I noticed the bases were not set perfectly square on their bases...oh well. On the subject of machining my Trijicon QD mount would not slip on. The actual slits in the rail are slightly under spec and tight. Nothing wrong with the trijicon as I mounted onto several of my AR rails and foun no problems. I brought the mount to a machine shop and had a guy custom file and ground the slits to get perfect attachment of the QD mount. Overall it would be an even better products if it was machined with greater precision and QC at the factory. Get rid of the moving windage feature and have it set to its perfectly square on a 77 once it's installed. Other than its pretty neat and would still pick this over standard ruger rings which I think are kinda low end and limiting for both the gun and the shooter.
Pros: Requires no gun smithing or special tools
Cons: Machining not perfect, certain qd mounts would not slip right on, adjusting the windbags features was tedious just to get the base straight along barrel

RugerR Comments helped.
you look closely at a Ruger scope ring, you will see a bevel on the tightening lug side the mounts on the receiver.
Also the recoil lug needs fitting.
Ruger needs to supply better mounts for their guns. Ruger was no help on this.
Optics Planet and Leather Wood were a help.
Pros: It is the only mount that works good with a M77 and a Aries 390 night scope
Cons: It took a little work to make it fit down tite

I got this instead of getting my reciever drilled and tapped...I worked for hours to get it all to fit and after 30 shots of 300wm the soft metal of the mount had dented where it was supposed to tighten so my scope went all floppy. This might work well on a light recoil rifle but now I have to get rid of this thing to do it the right way. They are discontinued for a reason.
Pros: looks cool
Cons: hard to set up, cheap for $100

was everything needed to make the Ruger into the tactical rifle it could always be
