Daniel Defense ISR: Integrally Suppressed Rifle

Daniel Defense ISR

Daniel Defense ISR

Daniel Defense has already established themselves as a first rate rifle and component manufacturer, so it was no surprise to visit their booth at SHOT Show this year and find another great design:  the Daniel Defense ISR.  The ISR, or Integrally Suppressed Rifle, was designed from the ground up to be one complete package, which I explain below.  The official model number is DDM4ISR 300.

The Integrated Suppressor (IS)

Matt Mozak of Daniel Defense walked me through the latest, greatest DD rifle.  The rifle is designed to be a weapon system, and not just a rifle with accessories added.  To accomplish this, Daniel Defense developed and added their all new Integrated Suppressor (IS).  The integrated suppressor is threaded, pinned and welded to the rifle’s proprietary lSR gas block, in what Mozak called a monolithic baffel.  So the IS becomes a permanent part of the rifle, and not simply an interchangeable accessory.  The length of the barrel and Integrated Suppressor together is 16.145”.

ArmaLite 300 BLK Rifle

Armalite 300 BLK Rifle

In keeping with the 2012 SHOT Show trend, I’ll be looking at ArmaLite’s offering in the newer .300 BLK chambering. I got a chance to handle their new rifle at their booth, and I learned a few things along the way. Before getting into the details of the ArmaLite .300 BLK rifle, I thought it would be interesting to share a little history on the AR rifle platform that has become so popular.

Armalite 300 BLK Rifle

AR-15 History

ArmaLite was a subdivision of the Fairchild Engine & Airplane Corporation back in the 1950’s. The founder was Lockheed corporate counsel George Sullivan, and the company’s first rifle designs were meant to be “light” survival rifles for downed pilots.

Olympic Arms K16 300 SST IN .300 BLK

Olympic Arms 300 BLK

[Aaron caught up with Olympic Arms at the 2012 SHOT Show and took a look at their new K16 300 SST chambered for the 300 BLK cartridge.]

By now most readers will realize that there has been an explosion in rifle offerings in .300 Blackout (BLK). The .300 Blackout cartridge came about to fulfill the desires of shooters who wanted to shoot .30 caliber bullets, but didn’t want to lose the capacity and weight advantages of shooting traditional 5.56mm AR-15’s.

Olympic Arms 300 BLK

The .300 BLK is a very unique .30 caliber cartridge. Instead of bulking up the casing and powder weights to accommodate the .30 caliber bullet, the .300 BLK starts with the same 5.56mm casing that is the standard for AR-15 platforms. From there the casing is necked up, or expanded out at the neck, to accept the .30 caliber bullet. The rest of the casing is the same as the 5.56mm casing along with powder weights. The end result is a .30 caliber bullet fired from basically the same casing as the traditional 5.56mm cartridge.

CMMG Revolution and M300 Rifles

CMMG Revolution

CMMG announced several new products at the 2012 SHOT Show.  Aaron caught up with them and took a look at the new CMMG Revolution and CMMG M300 rifles.

Being from Missouri I had to stop by and check out the latest from CMMG.  At the CMMG booth, I talked with Larry Wayland who sells their rifles through his retail store, and works closely with the CMMG staff.

The explosion of the .300 Blackout cartridge focused my attention to the CMMG M300, but while there Larry also showed me a very interesting new development that CMMG has been playing with. It’s called the Revolution model upper receiver and hand guard. This is an innovative AR-platform concept and CMMG has the patents. In addition to the .300 Blackout rifles coming out, the Revolution system is offered on their standard 5.56mm rifles as well.

REVOLUTION UPPERS

This new creation from CMMG allows for an ambidextrous upper receiver. Not in the traditional sense, but instead the receiver is milled to allow the same receiver to service a right-handed or a left-handed shooter. This innovation cuts an ejection port on both sides of the receiver. So the selected shooting configuration (right/left handed) has a bolt-on plate containing the ejection port and forward assist knob. The other side of the receiver has a bolted on plate covering that ejection port.

CMMG .300 BLK Rifles

CMMG AR15 300BLK

CMMG AR15 300BLKI may be the last person to have heard, but CMMG is making AR-style rifles chambered for the .300 BLK cartridge.  (As it turns out, I was not.  I got an e-mail from a guy who had been stranded in the arctic for the past six months who had not heard about these rifles either.)

Essentially, there are four variants of the M300 Blackout rifle.  All four of the carbines have 16″ barrels with 1:8 twist and a six position M-4 style buttstock.  Two of the models have a flat top receiver, no sights and a mid-length quad-rail.

The other two CMMG M300 versions have the flat top receiver, A2 front sight, Magpul rear BUIS and the standard carbine length handguard (no rails).
