It will because its based on the valve type.

A T98c is an inline blowback. They sorta function like a Spyder stacked tube blowback..but within one tube instead of two. An unbalanced spool functions much much differently. They aren't as violent of a mechanism, and will shoot infinitely smoother, as the thing moving back and forth is grams, not pounds...and will be moved by air, not springs.

In your T98 - your trigger tips your sear, your hammer uses the spring power to propel its self forward, striking the valve pin. The valve is opened, and air propels the ball forward. Excess gas is used to blow the hammer back, resetting it for your next trigger pull.

In a Rail - your air system and solenoid are using air to press the bolt sail o-ring (and bolt along with it) in the closed position. When the trigger is pulled, the solenoid shifts position, the air holding the bolt sail o-ring is vented, the rammer moves forward, and the air from the dump chamber is used to propel the ball forward. When the solenoid returns to the "off" position, air is then used to reset the bolt.

So - if you're just looking at the word air or Gas, you can see how much more air the Rail will use to cycle, as opposed to something like a T98.

But - in their nature, spool valve markers are usually less efficient than their poppet brethren.

Although a blowback should be very similar to an unbalanced spool in terms of air use. Blowbacks are the least efficient of poppets becuase the blowback air needs to not only be enough to overcome the weight of the hammer (often the heaviest individual part of blowbacks) but also the force of the springs.

During a maintenance, I ended up damaging my Solenoid gasket on my Reflex, so its unable to seal above about 250 FPS. When I finally scrape together enough cash to afford a $100 ANS order...for a $3 gasket... I'll see about borrowing a 47/30 tank or renting one and see just how far that gets me.

Awesome thanks again for the info guys once I'm done with Christmas if I have enough money left I'm buying the gun. How accurate do you think it? I have read a lot of reviews and it seems pretty mixed. I know I can hit 5/5 on a helmet at about 60 feetwith my 98 think it will get better with the proto?

On your 98, do you have stock barrel or aftermarket? What kind of paint do you generally shoot?

Paint is 95% of your accuracy, barrel is like 4%. Then 1% of everything else including the marker.

Thank you Miller. I had my typical long-winded response in the works...


Your shot-to-shot consistency will be somewhat noticeably better. Accuracy, assuming you're using an aftermarket barrel on both markers will be about the same.
