Things I liked: Power, power and more power. Accuracy is sharp. I like shooting it cowboy style with no bags on a bench or standing. Nice groupings despite a good kick. Fun lever action.

Things I would have changed: Not much. The air tube does not hold the fill 100% after filling but settles to about 3/4....I decided to fill it then turn it muzzle down before opening the pump release valve and it helps a bit. Not a big deal for me.

What others should know: Little loud for the backyard even with a DonnyFL moderator so warn your neighbors that your installing a deck with your pneumatic nail gun for a few weeks...

Things I liked: It's a pretty nice air rifle. Looks are not that important to me but it is really nice to see walnut in a plastic world. Power seems to be as advertised. Haven't measured velocity yet but 16 gr.pellets seem to go supersonic. Pyramyd followed my shipping instructions and rifle arrived in bush Alaska in about a week.

Things I would have changed: Kinda heavy but so what? Magazines could be improved with some type of detent to keep pellets from falling out. Somewhat difficult to insert magazine especially with scope in place.

What others should know: Cracks like a rimfire when fired. If you have that kind of money to spend, go for it. Durability yet to be determined, if it continues to function for a couple or more years itll be a favorite of mine.

Things I liked: Very powerful with the 43.2 grain end Jin pellets.

Things I would have changed: Package with a moderator.

What others should know: You need a very good back stop for this rifle if shooting on high power. As shipped it is in no way back yard friendly but with a moderator and a very strong back stop could be. I know when I shot mine I used hearing protection.

  • Victor from USA asked:

    Can you use the hand pump on the Seneca Sinatra 2500

    • Mark from USA:


  • Vladislav from USA asked:

    leaking air from fill port. New rifle.Any advise?

    • Mark from USA:

      If the air comes out as you try to fill. First ,with the air fill hose connected, tip the muzzle toward the floor. Tap the muzzle end fairly hard on a hard surface, board ,table leg,etc. This should help the check valve close. It sticks. If the fill is leaking out after the gun has been sucessfully completed the gun is defective. Return it.

  • Luis from USA asked:

    What the difference between sumatra 2500 carbine vs sumatra 2500 500cc reservoir? What is 500cc?

      The 2500 carbine is smaller . The air cylinder is 190 cc. The full size 2500 has 500 cc of air. Carbine is 18 shots per fill. Full size 2500 is 33 shots per fill.
