Hdb68 umarex testing 16j valve with co2 45 joules | chicago less lethal 

glad little ol me can help thanxx for tuning in :)

Yes indeed it does, they all come out then we use disc w/ c02 no disc w/ hpa i also use umarex stock o ring with c02 i found they work better with colder co2 vs duro 90

@@chicagolesslethal Thanks Brother! Hey, who's got the best projectiles for the HDR TR50 that will fit snug in the cylinder and through the tuning barrel. I ordered some from riotballs and they measured 12.3 mm and were supposed to weigh 4g but were only 3.6g. $70 I was pissed they fall right through the cylinders!💥🤣🤘

16j is the type of valve body, 45 j is the rating of projectile, i have seen increase in using the 16j over the stock 7.5 j
