I own a stag model 3 its a great gun so far its shot every piece of crap steel case ammo I have put in it. I even put lacquered steel case ammo in it trying to make it jam to see what it won't shoot so far not a single failure, as for upgrades shoot it and the decide I haven't done any internal upgrades to mine just a few cosmetic upgrages
I agree with Stagman. I own one as well a Left Hand version. Maybe 5k down the pipe no FTF or FTEs. as with any AR type rifle, you can customize it to your preference. No internal changes needed only external. Check out some other builds here on the forum and you will get some good ideas. Here is my transformation. Good Luck and get you some Upgrades..
Is that the right way to mount your front buis?? If so Im a dumbass and have mine mounted backwards on my rifles..
