On fully tuned SAEG M4, switched the begadi fly 5 to 4uantum
bucking, and it shoot (50m) straight as an arrow, max range 80m. Best upgrade.

it's a great product in general, but I'd like to highlight, that it allows you to have get great results with your original inner barrel. most great buckings (like the ML super macaron, or some Begadi ones) have wider contact patch than the window on your average inner barrel (they don't fit basically), so in order to get great results, you need to replace the barrel as well. thats not the case with the friction pro, I've tried it in an absolute low-end double eagle replica (everything remained stock except the bucking) and i've got outstanding results. it can be a game-changer for cheaper builds!

This bucking was installed in my mtw and has given incredible accuracy over the previous buckings I have used over the last couple of years. Very impressed with it!

works fine for me
