Q: Are the bolt carrier and charging handle included?
A: The bolt carrier and charging handle are sold separately.
I was hesitant to purchase this at first as I did not see anything regarding M4 feed ramps. I am glad I got this because it did have feed ramps and plus the rail is T marked. Fits well with my DPMS lower and barrel.
This is one of the nicest uppers I have used as part of a build. Everything mated up perfectly! I will definitely use Stag uppers in the future for builds.
Fit perfectly functions even better I will be purchasing more in the future
Ready to get the rest of my build just waiting on stag
The quality is Excellent ,Barrel fit is Tight which
is what I was Hoping for I shoot XTC NRA
Fit and finish are mil spec and worked great with my build. Fits well with my Aero lower.
