QUESTION:  Do I need to adjust my ejector?

ANSWER:  Yes, before firing your new pistol caliber lower we suggest you adjust your ejector.  Loosen the two screws holding the ejector in to where it becomes a semi-tight 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).  At this point you should remove one screw at a time without disturbing the ejector location and add locktite to the screws and tighten them back down.  This will ensure the screws will not back out over time.

 

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 specifications.

 

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.  The AR-9 BCG that we sell will work in both Glock style AR-9s as well as traditional Colt style AR-9s.  We can also modify your Colt style AR-9 BCG for you to work properly with both systems.

 

QUESTION:   What LPK will work with this lower?

ANSWER:   Although we sell a specific LPK with just the parts needed to build the G-9 lower receiver, any standard AR-15 LPK will work.  You will not need the magazine catch assembly, bolt catch roll pin, or trigger guard that are normally included with standard LPKs.

 

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.
