by 　 Scope

Day & Night rifle scope

ATN X-Sight II HD Maker Site

This is my best Scope ! Digital processing scope, it can calculate ballistic and it’s available each ammunition.  However this scope weight is heavy, over 1Kg.

Ratings: ★★★★★

Ballistic Calculator

Ballistic calculators were never this easy. No more charts, complex reticles, and calculators. The ATN Obsidian Shooting Solution does it all. Range in with your Smart Range Finder, enter your wind readings and let the Obsidian Core do the rest. Turn through the wind, change your incline angle, adjust distance and instantaneously your point of impact will shift to have the perfect shot every time.

It means this scope do not need MOA or Mil Raticle !

profile manager

Save all the ballistic and zeroing-in data in the profile manager for every weapon that you plan to use the X-Sight on. No worries about resetting everything up every time. Just create a new profile and you are ready to go.

TR77NPS

by 　 Rifle

Crosman 30131 TR77 NPS

This Rifle is powered by nitro piston technology. The air in the cylinder is already compressed and you apply more pressure to it when the gun is cocked.

Accurate Shooting can not be done by combining Center Point 3-9×40, Crosman Premier Hollow Point and this rifle. Zeroing is not stable……
The reason is still unknown.
