They also offer a switchblock option with some of their rifles, which is an interesting method to control the gas settings during different conditions a user may be required to shoot under (i.e. shorter barrels, suppressed, etc.). Noveske sets the standard for a Survival Carbine in Urban Survival and TEOTWAWKI situations – www.noveskerifleworks.com
This company gets mentioned twice (both in this section and the gas piston section) because they offer extremely high quality rifles that can operate as a gas piston system and then be “quickly” switched by the user to become a DI/DGI system or vice versa with the right parts.
Make sure you have gloves if you go the other direction or have been shooting a heavy rate of fire because that barrel is going to be extremely hot. www.lewismachine.net
This is the company that has been the standard for DI systems since the 1960’s with their introduction of the M16 and then the M4 in the 1990’s. This rifle is also the standard for the U.S. military and most U.S. law enforcement agencies as a patrol carbine. Their reputation and legacy speak for itself.
“Colt Defense LLC produces the M4 Carbine, M4 Commando®, and AR-15® series of semi-automatic rifles for use by US Armed Forces and US Law Enforcement agencies. As the exclusive supplier of the M4 Carbine to US military forces, the versatile M4 is built to strict US Government specifications. Furthermore, all of our rifles and carbines are built in our ISO 9001:2000 registered facility with the same high quality and reliability standards.” – www.colt.com
This is the company that started it all with the development of the AR10 and AR15 carbine rifles. They rose to prominence in the late 1950’s and sold the rights to these rifle system designs to Colt who subsequently was able to make them the standard for the U.S. military where although slight changes have occurred over the years, the basic concept and design remain the same. – www.armalite.com

If you see U.S. military personnel anywhere in the world using a Browning M2 caliber machine gun, 7.62 mm mini-gun or M16 rifle, chances are very good you’re seeing Sabre products in action – www.sabredefence.com
A favorite of some state and local law enforcement agencies, Bushmaster has a long history of making the AR-15 style rifles. You can find a Bushmaster Rifle at almost any gun store across the country and they have the status of the Chevrolet of AR-15 style rifles. Nothing fancy here but they work.
Bushmaster has recently launched a piston driven gun called the Bushmaster ACR which they licensed from Magpul, who called it the Magpul Masada. This rifle will compete against rifles from Colt, HK, and FN to replace the Army’s M-4. www.bushmaster.com
Probably better known for making revolvers, Mr. Smith & Mr. Wesson can also make a pretty good Survival Carbine as well. Their M&P series (Military & Police) are well thought of by rifle enthusiasts as a quality product. This is definitely a rifle you can depend on.
