Note:  This lower receiver is a take-off from a new KAC SBR rifle.  As such, the serial number begins with SBR.  You have the choice to receive this lower as a Title I or a Title II firearm.  What that means is that we receive this lower as an NFA item.  We can transfer this to your local gun shop as an NFA item, and you will complete the Form 4 as a short barreled rifle.  You can also choose to receive as a standard lower, and we will de-list the item with the ATF.  There is no waiting, as the lower can pass as a Title I, or standard lower, but the delisting process will take a number of months.  What does this mean to you?  Not much.  It only would matter if you choose to later Form 1 the lower as newly built SBR.  The actual delisting processes takes a number of months, but if you choose to treat this lower as a standard lower, you are perfectly legal, as long as you do not attach a short barrel to it.  All normal NFA laws apply.

This is a brand-new lower, which has been removed from a new Knights SR15 rifle.  It is 100% the same as a new item, except it does not come in a factory box and CANNOT BE BUILT INTO A PISTOL.

THIS ITEM CANNOT BE SHIPPED TO CALIFORNIA

THIS IS A SERIALIZED FIREARM.  It must ship to a Federal Firearms License holder.  No civilian exceptions.

Buying and shipping through Charlie’s is easy, but there is some information you need to know. Only a federally licensed firearms dealer may receive a firearm or federally regulated serialized item (like a receiver or suppressor). We cannot ship these items directly to you. Please follow these steps to process your transaction:

1)     Check your state laws to make sure the federally regulated item you want to purchase is legal in your state. Your FFL dealer should be able to give you all of the necessary information regarding your state specific laws. But, if we ship to your FFL, and there is a legal issue, we cannot accept a return. So please make sure that you know and follow your local and state laws.

 

2)     A quick google search will show you what Federal Firearms Licensed (FFL) dealers are in your area. When you are ready to purchase, contact the FFL dealer you would like to use and get their shipping address. During the check-out, put YOUR address in the “billing” section and the FFL DEALER’S address in the “shipping” section. If you don’t know your FFLs address, that’s okay. You can send the information later.

 

3)     After check out, make sure to contact your FFL dealer to ensure they will receive your shipment for you (most do this for a small fee, but you should always double check).

 

4)     Have your dealer send us a copy of their FFL to FFL@CharliesCustomClones.com. Charlie’s does not reach to your FFL (MAKE THEM EARN THEIR FEE!!!)

 

5)     Be patient! In order to ensure we remain compliant with all federal laws, our compliance department is kept separate from our sales and operations team. Please allow a few days for our compliance officer to verify all of your dealer’s documents and ensure all federal laws are being observed. You should hear from our compliance department within 3-4 business days. If not, feel free to reach out for a status update.

 

That’s it! We try to make this process as simple as possible for our customers, but if you are unfamiliar the process or have any other questions, please visit our How to Buy a Firearm page for more details.

California and New York residents please, click here. The process may be different due to state specific laws.

NOTE: The free shipping option does not apply to full rifles, unless purchased with a riflescope.  If you choose free shipping at check-out, we will bill you for shipping later.
