A while ago I made a video about the Nuprol BOCCA 12″ Rail System that I bought from Gunfire. Now that I have had a chance to play with the rail, I have released another video about it. The first video concentrated on the installation of the rail to my G&P upper receiver and the second video is a follow-up video of the small issues that I have faced with the rail since I have been using it. Both videos are available at my Youtube channel or you can view them straight from this post as well, just look below.
The outer finish is bronze or brown and it mimics the Daniel Defense rails that Madbull also makes. This rail does not have the real marking on it, thus having a little more affordable prize tag. The construction is aluminum and the rail feels really sturdy when handling it.
The installation was a real pain. To get the rail to fit to my G&P upper receiver I had to do a lot of filing and re-threading to make it sit and attach properly. While I was researching this, I found mentions that this rail will fit WE, G&G and small modification required with ICS replicas. G&P, at least the upper receiver that I had, required quite a bit of modification before installation was complete. With the mods though, the rail sits very well with the upper receiver without any wobble or play between the parts.
I also encountered some problems with accessories. While I was visiting Milgear, an airsoft store located in Oulu, we tried on several different rail covers for the rail. The only one that fit, with minor modification, was a DBoys modular rail cover, that you can see on the second video. The Eotech and AFG attach without any problems, as their attachment system is different from the Dboys rails. The rails attach with sliding them in place and attaching the last part, which has a small lever that locks the covers in place. The lever attaches to one of the grooves on the rail. These grooves seem to have their own specifications that are different from other rail brands. Nuprol makes their own rail covers as well, but I have not tried them. You would assume that they fit to the rails without problems. Other rail covers from different manufacturers seemed to have some problems and required slight modification when attaching them.
The rail has held up really well in use. I have been using it for a little over a month now and there are no signs of it failing. All in all, I am really happy with the purchase. Although the installation was difficult, it “brought me closer” to the rail and I like it even more having spent a lot of time installing it. Below are the two videos I have made about the rail. Take a look at them and place, like and subscribe to the Youtube channel. It helps me out a lot!
