I recently purchased a 25 Cal Armada off of eBay. I've been using it to shoot pigeons for my backyard. After putting several shots on Target and watching feathers fly and then seeing the birds fly away, I bought a chronograph. I got consistent readings of right under 700 ft per second. I was expecting to see closer to 850-900. I tested with three separate pellets. Predator polymag, Barracuda extreme Hunter, and Diablo exacts. Does anybody have information that would help me determine whether this is a problem with my particular gun that I purchased or rather is this to be expected with all 25 caliber Benjamin armadas?

If you have the manual, look at the portion explaining how to adjust the velocity. If you didn't get a manual, go to Crosman.com and down load the manual. You will have to increase the hammer spring tension which is explained in the manual.

Hi Griessy,
Naturally the wt of the pellet will affect how fps. I know those are popular pellets, but i am not familiar with the wts that you were shooting.
Heavier the pellet the slower it will go.
Naturally you can make adjustments to the gun to increase/decrease the fps.
I am shooting JSB 15.89 pellets at average speed of 738 fps over 627 shoots, extreme spread is 23, and the standard deviation is 4.
I'd like the gun to shoot a little faster, but it is deadly accurate, and i only shoot targets and this gives me 30 foot lbs of energy.
So should i tweak the gun?
I've resisted the urge to do so because of the dime size accuracy out to 50 yards, "If it ain't broke don't fix it"
The other slight challenge with the Armada is getting at the adjustments.
A knowledgeable poster on this forum listed the steps to get at them, i didn't copy them down and haven't been able to find his post.
You should be able to increase your fps but if the pellets you are shooting are 30 grains plus your speed is probably correct for your current settings.
I'd of attempted to adjust mine, however target shooting accuracy is most important and at 20 yards this gun stacks pellets, 50 yards a half inch group.

Thats the problem..... Im only getting about 700 out of it. I have been trying to figure out how to get the action taken off, but I'm having a hard time. The adjustments seem easy enough to make if I could just get the top off. The manual says to just take out the 1 screw by the air gauge, but that's not enough to release it

The 4 screws at the back (2 on each side)of the "plastic fore stock" have to be removed also! Then you have to loosen the set screw at the bottom of the "barrel band" and remove the fill "Cap"!
At that point the entire front end should slide forward and off! I don't think I have forgotten anything but it is possible.
Go over to Crosman and download the exploded parts diagram. Edit: for some unknown reason Crosman has removed the Exploded View and Parts List. PM me your e-mail address and I can send it to you! Edit again: Found it link below.

Thanks for that chart. I had already got everything but that set screw (part 14) .... That's where I got held up.

You dont need to disassemble the mrod to adjust it. There are adjustment screws and a port adjustment screw. Google "a team marauder tuning guide" and follow those steps. Just a side note the velocity isnt what allowed those pigeons to fly off they were bad hits.

Its the same thing in a diff stock and I think you have to remove the stock still to make tge adjustments. I did misread the post thinking you were asking how to take the receiver off the air tube tho when you were asking how to remove the stock. Sounds like you got the stock off. The A-Team tuning guide will get you the rest of the answers for tuning it.

Don't expect much over 850 fps. When my armada was stock and maxed out. I could only get 870fps with jab 25 gr.
