| Our new Quick Change Barrel
system has revolutionized the AR15 / M16 /
M4 Weapon System. This new upper receiver is
completely compatible with your M16 (small
front pin) lower receiver and allows you to change barrels in just seconds. This
makes it possible for the system to be extremely compact
and concealable, as well as giving the
operator the option of having multiple
barrels for multiple functions. The best
part of our QCB Upper Receiver is that it
utilizes standard M16 barrels! Take a close
look at the photos and you will see that the
barrel is a standard M16 barrel with the
Delta Ring, barrel nut, sling swivel and
front hand guard keeper removed. The QCB
also features 4 full length picatinny /
MIL-STD-1913 style rails that are actually
machined from the same billet as is the hand
guard itself. This means that there are no
screws to loosen or welds to break. |
 |
| No longer are the locking
arms exposed. The latest version of the QCB
(the QCB-C) has a slide cover retention
system, hard coat anodizing, reversible
locking cams, and 4 full length mounting
rails. To install your barrel in
our QCB Upper Receiver, all you do is lift
up on the safety locking bale, pull or push
the slide cover forward until the locking
arms are exposed, swing the locking arms out
to a 90 degree angle, insert your barrel, close the
locking arms and secure in place with the
slider retention system. Your barrel is
quickly secure and ready to go to the range.

| Each MGI QCB Upper Receiver
comes standard in a flat-top
configuration with MIL-STD-1913 rail
interface. The rail is marked for easy
removal and return of optics or accessories.
The special hand guard is equipped with
a 6" rail interface on each side and a 2"
rail interface on the bottom. The entire
unit is only 15" in length. |

|
The hand guard extension on the QCB provides full length continuous rail space
for all your mounting needs. |
Simply put, there isn't a better, quicker, or more
reliable QCB on the planet, even at twice the
price! |
