Gun Guys Obsess

Yes, we do. You know you’re as guilty as the rest of us. You could throw a cheap poly door, or any old metallic flapper on that ejection port, but you’re not going to be happy if you don’t do it right. Why ruin the whole project with an inferior port cover? You’ve gone to the trouble of picking out every other part of your new rifle for the best performance and appearance. Don’t mess it up with a cheap looking ejection port cover.
