This is one of my more recent creations. The Heavy Tactical Assault Rifle 5 is very slightly based on the sr25. It features two tactical rails on the top and bottom 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. H-TAR 6 is almost complete and the last 2 pics are of its progress.
