<p>The Smith &amp; Wesson® Response Series Semi-Auto Rifle enters the market with a bang in the PCC (Pistol Caliber Carbine) market. This rifle features the innovative FLEXMAG™ system, where you can use a wide variety of double-stacked 9mm pistol magazines to match use with your carry pistol. The controls offer familiarity to those used to controls on AR-15 platforms, making for an easy transition in use with minimal additional training. The M-LOK® handguard is ready for any desired accessories. The 16.5 barrel features a 1:10 twist rate and is threaded to 1/2-28 for common muzzle devices such as a suppressor or flash hider. The flat-faced trigger offers a clean, crisp break with a tactile, short reset. The rifle includes 2 FLEXMAG magwell adapters— one for M&amp;P double-stack mags, which is installed, and one for Glock 17/19 double-stack mags. Two 23-round M&amp;P series magazines are included.</p> <ul> <li>FLEXMAG system</li> <li>AR-15 style controls</li> <li>M-LOK handguard</li> <li>16.5 threaded barrel with 1:10 twist rate</li> <li>Flat-faced trigger</li> <li>Includes magwell adapters to accommodate S&amp;W and Glock 17 magazines</li> <li>Includes two 23-round magazines</li> </ul>
