430mm 6.03 Inner Barrel for VSR MARUI VSR-10 FN-SPR

Very impressed by the quality

Absolutely amazing product perfect for my JG bar-10 perfect air seal as compared to the stock part.

Barrel seems to be a lot better but I have only had a chance of testing it over a distance of 80ft in the garden so far. I put this in my well mb4402 combined with a maple leaf monster diamond bucking and other airsoft pro upgrades. The rifle was running at 485-87 fps but after installing barrel and bucking it has pushed it to 517-520 fps so need to install a 140 spring to bring it down for site limits but it will make bolt operation easier now. All but a few minor flyers were in a 3 1/2 inch group at that distance.
