ONE PIECE BASES Reviews & Ratings

I had no problems with this mount or the screws for that matter. I had called Farrells about the screws they are a T15 Torx and they come with instructions to use 20 to 25 inch pounds. If you torque them correctly and do not use the loctite this base fits so close it will not come off anyway I have been shooting it for 6 months without a hitch and took it off with no problem. But use the right wrench do not use an allen wrench. The screw are tapered to ensure that it centers the mount there is no lining it up needed. I also like the 1/2" hieght of the base my standard rings worked great for a 56mm scope bell.

I finally got to a range that let me shoot at 300 yards. The rail, Tact rings (Brownells), and the Bushnell 6500 elite are a great combo for the Rem 700 SPS 20" barrel. At 100 yds my cold bore was 1" high right. I adjusted my dope 4 clicks down/left and hit the bullseye on the 2nd shot. I did a 5 round group and all were touching. At 300 yds I was hitting 4" plates by holding over with my mildots. So far the screws have not backed out. There were guys with much more expensive rifles right next to me and they were not getting anything better than 4" groups at 100 yards. When I got done, they stopped me and asked about my rig. It's hard to just review the rail because other factors really dictate how the rail helps with the groups. Bottom line. I'd order this rail 10X over.

This base fits great on my Rem 700 SPS Tact 20" .308. However, the mounting screws were not that great. They are not meant to be backed out once you torque them down. Even a tad. The screw heads ended up stripping rather easily. I was trying to make sure everything was going to line up correctly (scope, base, rings) so I backed them out after all the parts looked lined up. I also wanted to apply loctite on the screws. That's when the heads ended up stripping out. The heads are a star allen head. I had no other option than to torque them down. The base comes with the tool. I think a regular allen head might have served better. As far as function, my cold bore (utilizing 30mm steel tact rings, FA Enterprises P/N 246-000-013, and a 30mm Bushnell 6500 2.5-16 elite with mildots) was three inches low at 50 yards but dead center. The second shot was right on top of the cold bore. I adjusted my dope in four click increments and dialed in nicely. The base and the rings were a great combination. I was not at a long distance range so 50 yards was the farthest shot I could take. As far as durability, I think the base will hold up fine. I'll deal with the screws when I come to that problem. I hope they don't back out on their own. The front ones backed out fine without stripping. If it weren't for the cheap screws, I'd give this product five stars. I wonder if Brownells would give me replacement screws if I asked?

So before I start Farrell did offer to fix this. I was looking for a base for my 700 Remington SPS in 223. I have other bases on my other 700 Remingtons but I wanted something a little easier to slip rounds into the chamber. So I saw this base and it was a little taller giving me just a little more room to slip a round in. Plus the big thing all the screws are the same size. No long one here or short one there all the same size. So the day I got my new base off to install it. No big deal all the screws are the same. Test fit and the screws are sticking up. Same size screws? Well grind a thread or two off and the screw is still sticking up. Head scratcher? Why are the screws sticking up? Take a another thread off. Same thing still up. One more thread I think should do it. Well of course I lost the screw. Great now I have to order new screws. Order the screws and a few days latter a package with new screws is here. Now I check the screws and they are the same length as the ones I had. Well let us give them a try. I screw them in and they are flush. OK what is going on? I look at the screws again. They are the same length. But the counter sink on the screws are not the same. My screws had a ridge on them causing them to stick up. The new screws had no ridge on them allowing them to sit flush in the counter sink properly. So in the end I had to buy new screws for a new base to get this to work. The others guy base is back on my rifle. It worked the first time. And this will go back to brownells thanks to the warranty they have. With the new screws I had to buy to make it work.
