Solid construction with an adjustable length of pull and cheekpiece height make this stock an excellent option for varmint and long-range target rifles. The 28 oz weight adds heft and balance to heavy-barreled rifles. Requires standard rifle-length A2 buffer, receiver extension buffer tube, and spring (not included). Includes mounting hardware and 2 ambidextrous sling loops. When compared to the standard A2 stock, the MagPul PRS length of pull adjustment goes from .25" shorter than the A2 to .75" longer than the A2.
