MAC 1 discovery ??

I have both guns.
Benjamin Marauder is a great gun for the money for sure and its a far better gun than the discovery. I only shoot my Marauder between 2800psi and down to 2100psi. So i only have 700psi to make up for my 20FPS spread for most accurate shots. The marauder is also a multi shot repeater with a more ergonomic stock than the traditional stock found on the discovery. Discovery being single shot and far cheaper made (i.e. Plastic trigger group, Metal finsh) It's a farcry from the capability you'd get from having a multi shot, More accurate, Ridiculously quieter, and adjustable two stage trigger all found in the marauder.
That's not to say the Discovery isn't a capable gun, It's great for the price and you can do plenty of good fun with it. But for the extra money you'd have invested in a TKO muzzle brake and MAC1 tune. You could have a marauder with more capabilities options.

Just my two cents.

The Marauder is a dual fuel gun so it can be tuned for 2K as a maximum fill if that is what the user wants.

I have Both guns in .22.
I can't 100% remember how many pumps it was. I'm remembering doing the math for it and i think it was 2.5 pumps per shot from 2100 back up to 2800psi. It is duel fuel, So you can use CO2 if you dont have HPA close to you. 

I own both also, Eric was spot on with his post. The Marauder is heavier and longer, going from 2-3k was around 110 pumps with the Benji pump. Hill pumps are more efficient like 3 to Benji 4 pumps. .177 /.22 / or .25 same tube same number of pumps, different tunes you can fill less than 3K to suit your needs. The new regulated guns look nice and are receiving great reviews. Pumping will get OLD, and if you do any amount of shooting a tank will be in your future, then the dilemma driving to a fill source. The cost, along with the time and mileage might sway you to your own air source.
