Q: How do I order a firearm / serialized lower receiver online?
A: Ordering a firearm online is easy, but not as easy as the media makes it out to be. Instead of shipping the item to you, we must ship to an authorized and Federal Firearms License holder (FFL). Before the order can ship, we will need a copy of the receiving party’s FFL. Copy of the dealer’s FFL can be faxed (216.744.8291) or emailed (

Q: My order status says “Processed”; what does that mean?
A: Some orders that we receive must first be double-checked to ensure that it was placed correctly. We check FFLs for firearm orders and to make sure that restricted items (i.e high-capacity magazines) are not being shipped into states that forbid them. Most times, when an order moves out of this status, it is getting ready to ship.

Q: When will my order ship?
A: Once payment and an FFL for your order has been received, your item will likely ship within 24 hours / one business day. We work very hard to get your order out to you, and apologize if there is a delay with it.

Q: Do you offer any quantity or volume discounts?
A: Yes. Quantity/volume discounts are unique to each item and are posted online if available. Sometimes, unpublished discounts may apply when making a large enough purchase. Please email us
at for more details.

Q: Do you have any dealers in my area on file already?
A: If you need help finding an FFL dealer in your area, please email us at with your
order number and zip code. We can look up the closest dealers to help facilitate the sale.

Q: I live locally, can I come by your store?
A: Almost all of our business is mail-order, but we do allow occasional pickups of orders.

Firearms can be purchased via the website and picked up by appointment only. You must undergo the required
instant background check at the time of pickup. Appointments are set at a first-come, first-served basis. You
must bring your driver’s license with you and it must contain your current address.

You must be a resident of Ohio and at least 21 years of age to pickup Handguns, Frames/Receivers, and
Pistol Grip Only Shotguns.

You must be at least 18 years of age to purchase Long guns (Rifles and shotguns).

FFL holders wishing to purchase and pickup eligible firearms may do so as well. Appointment is still necessary to
ensure orders are ready to go.

For safety purposes, please no children under the age of 18 on the premises.

Q: What forms of payment do you accept?
A: We accept Visa, Mastercard, Discover, cashier’s check, or money order.Your credit card
will be authorized immediately upon order placement.

Please Note: If using a prepaid card (e.g. Visa or Mastercard Gift card), most likely you must register the cardfor online purchases. Contact the card issuer for instructions on how to do so.

We can only hold a credit card order for 7 days.After 7 days, we must process the order, or it will be
canceled. You may reorder at your convenience.

If you want to pay with a cashier’s check or money order, we ask that you email us at and actually place an order with us that way we can provide you an exact total and an order number you can reference on the check.

Q: I tried to order, but my credit card was declined. What do I do?
A: If you contact your card issuer, they can tell you why the card was declined. Often it is because the billing address or card number/expiration/CVV was entered incorrectly. The card issuer can also stop the transaction if they suspect it was fraudulent. Your card issuer can assist you with any problems you may encounter. Your credit card will be authorized immediately upon order placement, but if the card is declined, the
authorization will be voided. You must contact your card issuer to resolve the problem.

Q: How will I know when my order has shipped? Will I get a tracking number?
A: If your email address is on file, you should get a shipping notice and tracking number emailed to you automatically once your order has shipped. If your order is going to a dealer and we have their email, they will also receive an email with the shipping notice and tracking number.

Q: How do I know if I am complying with my local and state laws?
A: It is up to EACH INDIVIDUAL to ensure that your purchase will not violate your local or state laws. For best results, consult any applicable local/state ordinances, your state Attorney General’s office, or a qualified attorney. NRA-ILA Guide to State Gun Laws is also a good place to start.

Q: Can you ship outside of the U.S.?
A: The exportation of firearms, ammunition, and firearm accessories is heavily regulated in the U.S., and we are not an exporter, so we cannot ship any of our products outside the U.S. We cannot ship to a freight forwarder who then ships outside the U.S. either.

Q: How can I cancel my order?
A: Orders placed with Go Ballistic Firearms may only be cancelled prior to the order having processed and/or shipped.

Q: Do you offer a reliable last round / empty magazine bolt hold open (LRBHO) system for this lower?
A: 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 incorporated 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 uppers are 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.

Q: Do I need to adjust my ejector?
A: 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.

Q: What type of magazines will fit in this lower?
A: 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.

Q: What bolt carrier group will work with a Glock magazine fed AR-9?
A: You will need an AR-9 Bolt Carrier Group that has relief cuts to clear the Glock style magazines. The AR-9 BCG’s that we sell will work in both Glock style AR-9’s as well as traditional Colt style AR-9’s.

Q: What LPK will work with this lower?
A: Although we sell a specific LPK with just the parts needed to build the GB-9C 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.

Q: Do I need to use a special buffer when I build my AR-9?
A: 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 we offer as well.

308 / 6.5 Creedmoor PRODUCT SPECIFIC FAQ:

Q: Is your upper and/or lower compatible with ____’s (insert ANY company name) upper or lower?
A: Unlike AR-15 platform rifles that share a common platform and general commonality of parts, pieces and accessories, the 308 (and similar caliber) AR platforms are uniquely designed by manufacturers and may not share common component parts, pieces and accessories. While some components MAY be interchangeable between models made by different manufacturers (Palmetto State Armory, Rock River, ArmaLite, DPMS/Remington/Bushmaster, Knight’s Armament, etc.) this commonality is by chance and not by design. Since there is no ‘mil-spec’ for a 308, manufacturers like us are faced with a challenge on what definition we use for a common denominator or should we just make our own. We, like many others, adopted the DPMS platform for our 308 platform since that is the most compatible platform with most other brands like DPMS, Aero Precision, Black Rain Ordinance, Ballistic Advantage, Magpul, etc.

Q: What lower parts kit (LPK) do you recommend?
A: Internally, we use the LR308 DPMS LPK and the M5 Aero Precision LPK. We have had success with others but you need to ensure they are DPMS compatible.

Q: Why is the bolt catch pin installed?
A: We HATE roll pins! That’s why we had a threaded bolt catch installed. 1/16” hex key (allen) will easily remove the threaded bolt catch pin.
