i managed to get a uk legal L129A1 (no gas system) had the choice of the sure fire flash hider or the bird cage one, but since the sure fire was an extra £120 i went for the standard one! my question is is the sure fire flash hider better ??
shit i just thought of that what a dick, all i know is that the bloke told me that i can 'upgrade' to the surefire flash hider at a later date so i assume it is just screwed in with very high strength loctite??
