Here are the most likely reasons you will get shootdown on your Wrath/Slayer/AR-1:
-Change your battery Check the battery Check the battery!,~ low voltage will be the most likely candidate for shootdown
-Make sure your tank is screwed in all the way~Air is not being released into the ASA.
-HPR or LPR is not high enough-~HPR works best at ~250 PSI and LPR until desired FPS is received.
-Lube your LPR and HPR, ~air is not recharging fast enough
-Get a board with Anti Bolt-Stick(ABS)-~You are getting bolt stick because of the temperature or lube you are using
-Lube the Ram with a good, consistent lube~-the lube is making the ram stick to the ram cap
-Stop playing in the cold, or use a cold-resistant lube-~this further causes bolt stick and reduces FPS consistency
-Use less lube-too much lube will "gum up" the ram, ~and cause more bolt stick
-Lube the noid-~Seals are not working correctly or the noid is sticking
-Check for leaks and holes in the LP hose-~air is escaping too much and air cannot get to the ram
-Check cupseals-~They may not be seated right.
-Clean the valve and lube the valve orings-~It is causing sealing problems.
-Get a new tank-~It is not recharging the air fast enough for your marker, or it is LP, not HP and has too little pressure when it recharges.
