I installed the 200% spring upgrade kit from Airsoft Extreme when I first purchased my APS and I've been pleased with the result. I could have gone with an even weaker spring and I still would have been pleased. So far I have seen no need to get the reinforced bolt lever or upgrade to a Zero trigger. If you treat the APS carefully you shouldn't need to spend a lot in replacement parts.
Every gun setup is different, but the 200% spring should put you over 450fps with .20's which might equate to around 400fps with .29's. Every approximate .05 gram increase in weight seems to drop the fps about 30. <b>This is just a general observation and not a rule.</b> Range should be at least 50 yards fairly accurately with consistent man-sized target hits out to 60 yards. Your accuracy and grouping are dependent upon the care you give your APS and the type of bb you use. I suggest that you spend a little money and get a few different weights of bb's. Since the hop-up is fixed you won't know if your getting th optimum range out of your APS unless you try different weights. Some guns like heavy, some like light. Don't take the hop-up apart and try to modify it, use the bb that it likes, not the one you like. Be careful when you're cleaning the barrel, you don't want to damage the hop-up. "Only mess with the fixed hop-up if you're prepared to replace it", that's my motto.
As far as bipods are concerned, most APS's I've seen with a bipod have used a common sling post attached to the underside of the stock. Its a simple matter of removing the stock; drilling a hole for the post; bolting the post on; then buying a bipod that will attach to the post.
Crap, cause i have just seen one that says it will work with ANY rifle that has a sling swivel stud, but on the exact same model from another seller i noticed a difference, "will fit on any CONVENTIONAL stock with a front blah blah blah"
guess im gunna drill into my gun By the way, the adapter that fits onto the barrel is ONLY recommended for use on pistols, you were right, it might mess up the gun
