Daniel Defense M4 Carbine, V5, No Sights, 300 AAC Blackout
Daniel Defense M4 Carbine V5, No Sights, 300 AAC Blackout

Daniel Defense’s new caliber option, the 300 Blackout, was originally designed to give the shooter a 30 caliber projectile which could be fired out of the AR platform without an increase in magazine size while still utilizing a standard bolt. The 300 Blackout is 7.62x35mm which gives the shooter similar ballistic qualities as the .308 and the 7.62x39mm, the AK round, without having to give up the light weight 5.56mm/AR platform.  The 300 Blackout can still utilize standard AR magazines without a reduction in magazine capacity. Unlike the 7.62x39mm, the 300 Blackout cartridge is still light on the shoulder with similar recoil to the 5.56mm.

SR-15 IWS E3 CARBINE MOD 2


The Knight’s Armament Company SR-15 line represents the pinnacle of firearms based upon the Eugene Stoner designed operating system. The Mod 2’s 16” chrome lined, 5.56mm NATO barrel is manufactured to military specifications, and features a proprietary mid-length gas system that increases reliability and durability while also reducing felt recoil. An improved E3 round-lug bolt design both enhances function and increases bolt life far beyond the industry standard. An ambidextrous bolt release, selector, and magazine release offer left-handed users the ergonomic advantages inherent to AR15-based controls, as well as giving right-handed users alternative methods of manipulation to increase efficiency of movement. The drop-in two-stage trigger serves double duty as an aid to long range precision marksmanship while enabling surgical speed shooting at close range. The Mod 2 update introduces several notable features to the SR15 IWS line: a URX4 handguard with Keymod accessory mounting points for-ancillary device attachments increases cooling characteristics and reduces weight and bulk compared with standard 1913 rail attachment methods. A Mod 2 gas system with a proprietary design minimizes leakage and ensures more consistent operation in harsh conditions. A gas block secured with a locking ring instead of taper pins increases barrel rigidity and eliminates the need to custom fit the gas block to the barrel. Included parts and features, such as the two-sided receiver end plate QD sling swivel mounting point, collapsible six-position SOPMOD stock, hybrid ambidextrous selector lever, and folding 200-600 meter sights, round out the package to deliver a cutting-edge carbine right out of the case.
