Ruger's concept of a lightweight, small frame AR style rifle chambered in .308 - 7.62 is a good idea. However, shooters have learned by hands on experience that the functional reliability and quality control of the factory rifle have been problematic. Shooters have reported complaints of unreliability, failures to feed, failures to extract, failures to eject, inaccuracy, loose and broken parts, gas leaks, poor trigger action, etc., etc. Listed below are links to videos of SFAR shooters having problems with the rifle.
Shooters have asked DLS for solutions, and DLS has delivered by applying decades of AR experience to solve the problems. Extensive live fire testing has proven that the DLS Enhanced model rifle solves all known problems to date. Time, effort, experience, and individual rifle quality control and testing are all required to deliver a mechanically safe, reliable and accurate rifle to the client. There are no production lines at DLS inc. It takes more time and effort to do things right, but doing things right is the right way to do things. Serious shooters understand the value of handcrafted firearms.
Field experienced shooters know that a rifle is often carried and handled far more than it is fired. During hiking, biking,camping, riding four wheelers, horse scabbard carry, and getting in and out of the truck, etc., it is possible to unknowingly activate the magazine release on rifles and lose the magazine and ammo when you need them most. To solve this problem DLS has designed, and can incorporate a magazine lock into the receiver of the rifle. This allows shooters to insert and lock in place a loaded magazine. The lock prevents the magazine release button from releasing the magazine, unless it is purposefully unlocked first. Locking or unlocking the magazine does not require tools, it can be done by hand in seconds. Then conventional loading and unloading can be resumed. The lock can be used or not as the situation dictates.
Enhanced SFAR rifles are completed one at a time for individual clients as orders are recieved. Various optics, lights and colors of cerakote are available. Prices vary depending on features.
