My WK180C factory handguard screws loosens after each range session. The cheap screws cannot handle the recoil and back out, making the handguard come loose. Any ideas on how to permanently tighten the handguards? I used blue loctite but it seems the barrel heats them up and they still come loose. Should I get the TNA handguard?




























, they really stays in place when tightened (I used 5nm.).
