So the other brand muzzle brake have very big holes and will be tricky to adapt.
Here is a picture with Hooben muzzle brake (grey), Tamiya (alloy) and Henglong/Taigen (black).

Hello, the cheap Tamiya alloy muzzle fits quite well, a little epoxy to hold it in place and it's ok.PainlessWolf wrote:Good afternoon,
Ad Lav, great answer!, that should have been obvious to me. ra272, we could probably adapt either of those two by using a couple of brass rings cut to progressive size out of some tubing from a hobby shop. The Tamiya is probably closer to the historically correct size than the one that comes with the kit but having said that, the Taigen one would work for me. I love a big muzzle brake. ;o) How about Ludwig's site? He carries metal accessories and parts for this Hooben kit.
