Introduction: H-TAR5 (Heavy Tactical Assault Rifle 5)

About: My names John,I've been building with knex for 5 years And am currently working on a lever action tube fed shotgun =D
This is one of my most recent creations. The HTAR-5 is very slightly based on the sr25. It features two tactical rails on the top and bottem that allow the addition of red dot sights,scopes,bayonets,grenade launchers and anything else you can think of. Another feature of this gun is the flip up sights and five round short mag that can easily be extended. This gun has a very long pin pull which is allowing it to get 55-60 ft. Tell me what you think should be changed,or any addons you would like to see on this =D
