Product Description
Allows most AR-syle rifles (retractable stock models only) to be retrofitted to the same pusher rod system used in the MR556A1 and HK416. Includes complete MR556A1 Upper Receiver/Barrel Assembly with HK 16.5 inch cold-hammer forged barrel, upper receiver with forward assist, extended convertible charging handle, HK Free Floating Rail System handguard, HK Bolt Group Assembly, HK Proprietary Buffer, and HK Buffer (Action) Spring. Due to the shortened length of the HK buffer and HK (action) buffer spring, these parts do not work in fixed stock AR-type rifles. Installation of MIL-SPEC hammers in non-HK lower receivers is required for reliable function. Additionally, the MR556A1 Upper Receiver Kit does not work in lower receivers with fully automatic or selective fire mechanisms.Limited Lifetime Warranty.
