Federal law requires that you be 21 years or age or older to purchase a stripped
receiver or frame. If a frame or receiver can only be made into a long gun
(rifle or shotgun), it is still a frame or receiver not a handgun or long gun.
However, they still are "firearms" by definition, and subject to the same GCA
limitations as any other firearms. See Section 921(a)(3)(b). 18 U.S.C. Section
922(b)(1) makes it unlawful for a licensee to sell any firearm other than a
shotgun or rifle to any person under the age of 21.

QUESTION: What type of magazines will fit in this lower?
ANSWER: The lower was designed to fit and drop
free factory Glock small frame pistol magazines. It has also been
thoroughly tested with Magpul GL17 9mm pistol magazines to fit and drop
free. Although it accepts and shoots other aftermarket magazines
(Promag, KCI, Kahn, etc) some slight modification may be needed to get
them to drop free from this lower because of the varying width
measurement we have seen when checking these magazines to Glock factory
QUESTION: Do you offer a reliable last round / empty magazine bolt hold open (LRBHO) System for this lower?
ANSWER: YES – After watching several companies try
and fail to incorporate a RELIABLE last round bolt hold open (LRBHO)
system into their lower receivers we decided to take a different
approach and will be incorporating our LRBHO technology (PATENT PENDING)
in our matching upper receivers. After rigorous testing and hundreds
of hours of research and development we feel that this is the best
option for LRBHO on a Glock magazine AR style firearm. Our upper will
be compatible with other manufacturers lower receiver that either don’t
have a LRBHO or you can scrap the non-working LRBHO out of your existing
AR-9 Glock Mag lower and solve the issue of not having a 100%
functioning LRBHO. For more information on our matching AR-9 Upper, please CLICK HERE.
QUESTION: What bolt carrier group will work with a Glock magazine fed AR-9?
ANSWER: You will need an AR-9 Bolt Carrier Group
that has relief cuts to clear the Glock style magazines. Both AR-9
BCG’s that we sell (CLICK HERE for AR-9 BCG’s) will
work in both Glock style AR-9′s as well as traditional Colt style
AR-9′s. We can also modify your Colt style AR-9 BCG for you to work
properly with both systems. CLICK HERE for more details on that service
QUESTION: It seems as though my BCG may be hitting or rubbing the ejector on the lower, how can I fix that?
ANSWER: Loosen the two screws holding the ejector in to where its a
friction fit. Ensure the ejector is seated all the way to the rear and
all the way down in the pocket. Close your upper onto the lower with
the bolt all the way forward. SLOWLY cycle the bolt in and out about
1/4 of the way back a few times then let the bolt close all the way and
tighten the ejector screws. They are cupped to get a good grab on the
SS ejector, so only hand tight or you risk the chance of bending the
ejector over. Any slight rubbing at this point will wear in the ejector
after a few magazines are cycled through the gun. If you see excessive
rubbing you can also file down the top corner on the left side of the
ejector (shooters left)
QUESTION: Do I need to use a special buffer when I build my AR-9?
ANSWER: Although its not technically required, it
is advised that you either use a 9mm buffer (longer and heavier than
carbine) or a spacer in your buffer tube before you place your spring
in. The reason for this is to limit the BCG travel to the rear so it
doesn’t come back forward and smash the bolt catch hard enough to break
it. The 9mm BCG is shorter than a standard BCG. You can use a carbine
buffer with a spacer (WHICH YOU CAN PURCHASE BY CLICKING HERE) or simply
stack between $1.25 – $1.75 of quarters in your buffer tube.
