Rafael Silva Coelho (Wimbledon, GB)

Used BT52 rail before to mount a monopod at the stock of a FX Wildcat MK3, this time I measured the gaps at the but stock in my FX Impact M3 and the BT52 rail fits just perfectly.
The reason why I chose this rail is the compact size, very minimal footprint, the hard anodizing coating is very high quality, matt finish and durable...nothing like those chinese shinny picatiny rails on Ebay that start peeling off after a couple of quick connect and disconnect of an accessory. The price is high, but if youspend a good amount of money in a firearm, do not save on the accessories, they are equally important...and if you appreciate quality engineered products, you will understand what I am trying to convey here with my review. Service from Xtremetactical was also top notch, it is always delivered with a bit of delay, but I do not mind waiting a few days.
Ps: I added a few pictures here, I also made 1mm thick rectangular rubber gasgets to go between the rail and my stock, to avoid scratching it once you apply proper torque on it.
