If you're serious about building a period-correct, authentic-looking M16A1 rifle, then little components matter, like the lock washer used to attach the flash suppressor to your clone's barrel. Luckily, Brownells offers a period-correct lock washer for the flash suppressor used on the original M16A1, allowing you to build your perfect clone.
