New build 11.5 Alexander arms barrel

[A5BLASTER]

thanks again for the reply. I will go with the Atlas when they come back in stock. I definitely want an adjustable gas block even though I’ve never used one yet.
So do you know what size handgraurd I need So it will fall in behind the gas block?

What's your gas length?

As stated in my last reply a 7 inch falls behind the gas block on a carbine length gas system and a 9 inch falls over the gas block on a carbine gas length system.

The 12 inch will cover the gas block on a mid length gas system.
