Item # 298934 Style HCK-81001053 UPC 642230272477 Condition New Manufacturer [HK USA](https://www.kygunco.com/brand/hk-usa) Model MR762 A4 Round Capacity 10 Caliber 7.62x51 NATO Action Semi-Auto Barrel Length 13 in The latest update from HK-USA to the commercial variant of the legendary HK417, the MR762 A4 represents an enhanced example of “no compromise” HK performance. Chambered in 7.62 x 51mm, its short-stroke gas piston operating system does not impart hot carbon fouling back into the action, allowing the weapon to run longer, with less maintenance and with less wear on internal components than direct-impingement ARs. Its adjustable gas regulator allows the operator to tune the action specifically for suppressed or unsuppressed operation. Fully ambidextrous controls, lighter weight and a slimmer profile make the new A4 easier to operate, manipulate and employ. For those who demand an AR with unmatched capability and uncompromising reliability and durability, the MR A4s remain the top tier solution. - Overall height: 7.75" - Overall width w/lever: 3.23" - Picatinny Length: 23" - Without magazine: 8.8" ** WARNING: This product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
