So when I purchased my SLR I was keen to immediately strip it down and start increasing FPS and accuracy (as we all do) not knowing a great deal about how different parts influence the two attributes I was keen to improve. So based on advice from the seller I have over the past couple of weeks done the below.
On the first tare down I added:
Cylinder ORing (brown)
AusGel 1.18 spring
MST 100% cylinder
Trimmed 3mm off Tappet plate
Heavy duty tappet plate spring
Lithium grease on stock cylinder head to improve the seal
After doing these mods I was achieving a consistent 260 FPS and a very impressive Accuracy over 25 metres. Gels were AusGel pink limited addition.
After a week of daily use the accuracy changed significantly which made it much less desirable to use the ■■■ so chasing it back and thinking that the lithium grease purging out the cylinder head was the narrow minded reason, I purchased an alloy double O ring cylinder head and have been chasing accuracy ever since.
During my endeavours I have glued in the barrel thinking there might be something there causing it and also adding a metal spring retainer that has a bearing. Thinking maybe the spring was rotating and binding slightly (based on advice). But unfortunately nothing has helped so far. When I shoot the ammo either rapidly curves down right from the barrel exit with hip up or without hop up in every which way direction except where I aim (1-2metres over 25metres)
So I’m thinking I have too much surplus air exiting the barrel with the gels. Thinking my next upgrades will going to a 7.3mm barrel with an overall length of 400mm( stock is 7.5mm 330mm long)and see if that improves my accuracy.
I’m not keen on dropping FPS unless it’s a last resort as hitting a target is undoubtedly the aim of the game.
If you’re still reading my post thanks and appreciate any advice on my build.
