The ARES Defense Sport Configurable Rifle (SCR) is a semi-automatic rifle that employs many of the virtues of the AR-15 platform and takes AR-pattern magazines, but does not have any of the "features" that are frequently singled out by anti-gunners. That means the SCR is legal in all 50 states.
In essence, ARES took the front half of the AR bolt and mated it with a tail, as is commonly used in self-loading shotgun designs. Instead of an AR buffer tube, the tail on the back of the firing pin matches up with a recoil-spring and cup assembly that would be familiar to any semi-auto shotgun owner. Also, the lower receiver has been reconfigured to match up with the standard rifle stock. The fore-end is a slim and svelte Magpul, available for both carbine and rifle lengths. The upper reciever has a standard Picatinny rail. The SCR ships with a 5-round magazine, but higher capacity aftermarket magazines are available.
