Nice adapter for the C02 Air Javelin ,held pressure overnight
Nice adapter, held pressure overnight...threads nice....put a little Super Lube Oring silicone on the Orings...worked great. One tiny complaint, the plastic rail ( On the gun ) it slides on is undersized...so it has a wiggle...screwed down. Just took 2 small strips of servo tape, put it on the adapter where it meets the plastic frame of the gun...no more wiggle whatsoever...easy and solid. ... show more
