I recently purchased an A-5. I have put about 2000 rounds thru it and have noticed a few issues that I could use some help resolving.

Gun: A-5 E-Trigger with a Smart Parts 16in Progressive barrel. After market stock (not gas thru), HPA (800 psi).

There were several people with A-5's using the same paint I was and they did not experience the issues that I have.

Issue #1: Velocity fluctuation. In the beginning, I couldnt get the rate over 250 fps. After streaching the rear spring, I am able to get the speed at acceptable levels, but the range is too much. Some speeds will be at 250 fps and some will be at 275 fps.

Issue #2: Ball breakage. It seems that when the gun is any other mode than semi, the ball breakage (in the barrell) increases when the ROF increases.

Are these two issues connected?

What mods will I need to do to correct the problem(s)?

Would upgrading the bolts help with the velocity?

Are the balls breaking because of the barrell?

Thanks, Dave

A quick way to tell if ball breaks are happening in the barrel is to shoot the marker with the barrel removed. No breaks, then it is the barrel. I'll leave the other issues to more knowledgeable people.

The future holds:
X7 Vented Cylinders for both my A-5's

ususally adding "mods" is not going to fix anything. the A-5 should work just fine in stock form

why you don't have great velocity...i can't tell you. i would look into getting a stiffer spring, or adding spacers behind the drivn pin and spring. i have found dropping 2 bb's into the hole in the endcap works pretty well and is usually worth 30-40 fps. i might say the reason for the jumps is because your spring was stretched and is not very stable.

get a stiffer spring, or spacers. now that th spring is more compact you will be shooting higher speeds, i would like to know if you are still having the same inconsistancies.



for the breaking paint...i would look to the barrel first. there's a chance that the paint was too large for the barrel. was all the breaking occuring inside the barrel? or was the cyclone and bolt chopping the paint? where was the goo at? if its in the barrel then its the barrel. might be too tight fitting for that paint, also check for burrs, lips, anything "ugly" inside the barrel what might cause breaking. its possible is was made poorly.

to resolve your first issue it sounds like you need a regulator.. Palmers makes an awsome regulator. What it does is regulates your air to make you shoot more consisitant and not have a fluxuation. for your second problem. what kind of paint were you using? was it to big ? I have noticed that when its colder outside paint seems to break easier in the barrel.. Also was there anytype of burr or anything to make the paint break in the barrel?

his hpa tank should already have a regulator. the need for the palmer's in terms of that kind of fluctuation control would generally be associated with the use of co2 as a propellant.

i had the same prob when i use to use a smart parts 14" tear drop try using your stock barrel could be the barrel or type of paint your using my prob was the paint draxxus blaze works real good with the progressive and tear drop hope this helps

not only that, but he's experiencing low FPS issues. adding a regulator would only cause more trouble for him in tht area.

As for the velocity problems, at first I couldnt get over 250 fps. I had to stretch the spring so that I can get to atleast 280 fps. Now when I shoot, it can go from 250 to 290 and the fluctuation is more evident when ROF is increased. Would changing the bolt or power tube help this.

As for the breaking of paint, the balls are being chopped. The balls seem to break toward the end of the barrell and when I am shooting at high ROF. I did try the stock barrell with the paint and the accuracy was worse than the aftermarket barrell. The other guys were using the same paint with a flatline and didnt experience any breakage.

What type of paint was being used?
