Any standard flat top upper will work usually called A3 or A4 uppers. Also your bull barrel will not be a problem, the receiveres are the same as far as threading, etc. You will need an action block, vice, and barrel wrench, and whatever tools you need to take your gas block off with. It is something you can do yourself. Good link that shows how to remove a barrel, etc. scroll down untill you find it. Good Luck |
It is just the A4 Upper. It does not have a barrel attached so you could attach whatever barrel configuration that you would like. Give me a call and I'll get ya taken care of. |
