Up for grabs is copious amounts of HK awesomeness.See the description below from the manufacturer. I have added a few upgrades to this rifle. I replaced the Magpul stock with a sweet little stock from Larue Tactical, added an extended bolt release, a gunfighter charging handle, replaced the dust cover and added an Aimpoint patrol optic.Contact firstname.lastname@example.org. I also have a second 30 round HK magazine and the original HK gun bag. This gun was bought new and very well cared for and loved, I shot it maybe 100 rounds sighting it in and the moved on.Selling to help pay for a new boat.Using the HK MR556A1 and input from many competitive shooters, the Competition model was developed for both casual shooters and the most demanding competitor. It retains many standard features of the MR556A1, including a German-made long service barrel produced by HK's famous cold hammer forging, and HK's piston operating system which uses a gas piston and pusher rod to improve reliability and reduce cleaning/maintenance. Ideal for 3-gun matches, the Competition Model is optic-ready, and includes a free-floating, 14 Modular Rail System (MRS) handguard which is lightweight and easy to customize while presenting a more ergonomic, comfortable handguard surface compared to rectangular full rail systems. The extended magazine release allows for quick magazine changes, and an innovative compensator by Operator Suppressor Systems Inc. (OSS) replaces the standard MR flash hider. This Competition model includes two 30-round magazines.When shipping Firearms: We ship FFL to FFL only.
