BIG BORE GASSERS

      If you're looking to become well-rounded with running large-frame gas guns at extended distances then look no further!

Course description

      This 3-day course is very similar to Precision Bolt Gun, but with the main focus on the nuances of precision behind driving a Large-Framed Precision Gasser (SR25, AR-10, SCAR-17/20, etc.). Due to some of these nuances as well as realistic precision capabilities of such rifles, and the overall demand of teaching a “large-frame gas gun” course, I decided to create a separate course all together. This class is NOT exactly tailored around a “battle rifle” set up with grouping capability of 3 MOA or better. If your rifle/ammo meet the 1.5 MOA requirements, you’re good to go. For most situations, I believe in 10-round groups for testing, however if it meets the requirements in 5,  you're fine with that as well.
