All Rifles are professionally built to Mil-Spec Standards, the only difference between this and the Military MA Deuce is that it is semi auto & legal for civilians to own. They are Magnesium phosphate finished (Military Parkarized )and offer a highly durable and original style. All rifles go through a quality control check before leaving the facility, and are test fired with at-least 40 rounds each to insure customer satisfaction.


PLEASE NOTE:  If you live in a magazine restricted state and the magazine that comes with the firearm would be illegal, we will remove the magazine from the order and ship the firearm to the dealer without the magazine. We cannot ship magazines to out of state addresses and we cannot alter or customize magazines at this time. There will be no discounts for removal of magazines or other custom magazine options offered. If you are located in California and are purchasing a rifle we will be glad to send the mag to the FFL dealer as a parts kit. It is your responsibility to discuss this in advance with your dealer. We do not offer parts kits to any other states since it is only legal in CA. 


It is your responsibility to be familiar with your current local gun laws BEFORE placing your order. Please feel free to email us with questions you may have.
