I installed the RS!Regulate AK-310 base and AKR top rail in preparation for the new beautiful Vortex HS-T 4-16x44mm scope the folks at Vortex helped me select.
The RS!Regulate system is genuinely impressive. By installing the bottom rail, you then have options about the front to back location of the AKR rail as well as left to right. If you wanted to, you could install a shim if you needed even more vertical adjustment on one end or the other to compensate for a poorly placed side mount on the rifle.
The only hangup installing the AR-310 base was a poorly formed rivet with a protruding portion of the head that the base was hanging up on. I ground that portion flush and then used Brownells’ Oxpho blue to touch it up. When steel is freshly ground, I apply the Oxpho cold bluing liquid with a Q-tip and the steel instantly turns black. I let it sit for about 30 seconds and then wipe it off and apply oil.
The AK-310 base slides on like any other ComBlock side mount but it has a very nice cam lever and an adjustable bolt on the bottom to get the cam lever nice and secure. Once I got rid of the protruding rivet, it slid right on and then I adjusted to bolt until it was nice and snug when I flipped the lever.
The AKR looks like a reverse picatinny rail on the bottom and interlocks with the rail top of the AK-310. I had to move the AKR all the way to the front to compensate for the M77’s rear mounted rail. The AKR is held to the AK-310 by 4 screws in grooves. The beauty of this is that you can really dial in the centering of the scope. I was able to get the AKR exactly centered over the M77. Now, once you have it located, they give you two staking pins to drill and install to permanently locate AKR. I have held off doing that I may need to move it around some but went ahead and applied blue Loc-tite on the screws.
With the rail centered and ready to go, I turned my attention to the HS-T scope from Vortex. This is one heck of a nice scope. I opted for the MilDot reticle and a 44mm objective to ensure I cleared the rear sight leaf. In hindsight, I could have gone with a 50mm objective as there was plenty of clearance. I own a Vortex Sparc II red dot and liked it. This is my first actual Vortex rifle scope and I am very impressed.
I used 30mm medium rings to mount the Vortex. They are extremely beefy tactical rings from UTG. You may laugh but I have had very good luck with their rings. The only shortcoming this time is that they were so long (from front to back) that I ate up some precious real estate for sliding the scope forward. It all worked out in the end but for awhile I wasn’t sure if I could get the eye relief right but I did.
There was some give and take as I moved the scope rings and the AKR around. The photo above shows the AKR sitting in the last groove. I wound up actually having it overhang by one by the time it was all set.
So, the scope lines up beautifully with the 1″ cheek riser on my Ace skeleton stock. I have heard that the Vortex scopes have good optics but that is an understatement – you have to look through one to realize how good it is – very bright and clear. Couple that with arguably one of the best no questions asked warranties in the industry and now you know why I bought it. I did a ton of research before doing so as well.
Only one more thing to do now … find the time to take this hammer shooting with multiple brands and loads of good ammo to stretch its legs.
In the very near future, I will swap out the medium rings for a low offset AR mount so I can get the scope closer to the center of the bore plus move the scope just a bit more forward and that will be a post for another day.
One final comment, Ace Riflestocks emailed me the other day and their modular Zastava adapter is back in stock. If you are looking for one, I would recommend checking them out as well as Desert Fox.
