Supposed to be VFC compatible. Requires modification and removal of steel from the base collar first. Unfamiliar threaded insert to forward end of barrel. Not an airsoft barrel feature. Very heavy. I do not recommend this product.
I am hungry and want to eat cheeseburgers. These glasses will protect me from the crumbs.
okay quality but it doesn't fit
Mounts without problems, and gives a S.F. look ;)
