-Aero Precision Scope Mount -Nikon 3-12x42 AR Scope This precison rifle was built professionally at Parabellum Armory for the purpose of reliability and accuracy beyond the typical 200 yard platform, but into 600 yard range or more, accurately with the correct optic. This is not a starter gun, nor a cheap truck gun. This is an extremely well built rifle with a top grade finish and finely engineered parts. With over $2000 invested into the weapon, not including the scope, it is a phenominal deal for under $1700. This weapon has only had 90 ROUNDS (3 different brands/gr ammo with ZERO failures)through it, which were to ensure reliability from the start!!! It has not been to the range with this scope, so its not even sighted in yet! It is a practictically new weapon for a used weapon price. Make me an offer I cant refuse..
