Reviews & Ratings for Evolution Gun Works HD Picatinny Scope Mount, Ruger — 5 reviews — Page 1

I recently purchased a Ruger No. 1 in 45-70 and wanted a picatinny rail to give me enough elevation to mount a 50mm Objective scope. The first problem here is that the rear of the rail DOES NOT sit flush with the barrel. All the holes line up correctly, but the rear of the rail does not sit flush with the barrel (can see the screw and light when looking under the rear of the rail). This was supposed to fit the "S" designated barrel, that is why I purchased it. Another thing to be very careful of in general when mounting any scope on a Ruger No 1 is making sure to get that scope back far enough to be able to see well through the scope without climbing up the butt of the rifle. Many variables come into play with mounting scopes on Ruger No. 1 rifles. My biggest bit of advice is to purchase off-set rings and no larger than a 40mm objective scope (bell of scope can hit the barrel, and you may run into issues with running out of elevation adjustment if the scope sits too high off the barrel). Purchase one with as much eye relief as possible and mount that scope as far back as possible.

High quality but I ordered the wrong rail. Opticsplanet were kind enough to allow me to reorder the correct one and I am anxiously awaiting the next one.

The rail itself is a quality made item. This is going on a brand new rifle that I bought in about 1987. Apparently, the profile of the rifle, where the barrel goes into the receiver, changed at some later date on #1's. Mine is beveled up the sides and square for about 5/8" on the top. The radius on the bottom rear of the rail hits this square shoulder before the rail can seat. You either have to do a lot of filing or take it to a machine shop to be milled. Mine is at a machine shop now. This is a 270 Winchester with a 26" barrel. Using the stock rail and Ruger rings you can only use about a 6 power scope. My Leupold goes up to 14 power and you have to go into contortions to get close enough to get a full picture. A Leupold AR one piece base and 30mm rings has a 2.5 inch offset. Turn it around backwards from the way you would put it on an AR and the scope can be moved back to where you can get a full picture. Walla!!!

I will give EGW the benefit of the doubt and assume Ruger has several barrel profiles for the no.1 and this rail is meant for the 308, I tried to mount this on a ruger no 1 chambered in 6.5 creedmore and the picatinny rail did not even come close to matching the contour of the barrel. The bottom needed to be completely reshaped in order to make full contact with the barrel. In the end I am pleased with the result but this was not a simple job for the average user.

I've been trying to do everything I can to make my rifle 1/4 MOA or better at 500yds. I purchased this scope mount in conjunction with a pair of Seekins 30mm scope rings and couldn't be happier. The rail has a nice finish out of the box, yet I was prepared to bed the rail to hlep with any possible stress relief from torqueing from mounting. Surprisingly, there is no flex or warping of this rail so it did not need bedding to the receiver! The only downside I can see is if the scope is on the shorter side or has a really steep angle for the bell of the objective lense, there may be some clearance issues. If I build another rifle or help a friend with theirs, this rail will be the first one I choose for mounting any scopes.
