Confused about G&G GBBR Raider-L V.2 fill time

[RogueCow]

Hey everyone,

I recently purchased a new raider-L GBB and before receiving it I want to clarify the fill time for propane in the mag.

The manual says never fill more than 4 seconds, some other google searches have said 30 seconds or more in 8 second bursts... so does the manual mean never fill consecutively more than 4 seconds?

Im hoping to get some clarification from someone who owns and operates these gbb guns before I receive the gun and blow the internals or something.

I know these arent "true" GBB guns and may differ from the more common high end gbbr systems, so again; im looking for owners or users to sound off

Fill it till you can't hear gas flowing out of the bottle anymore
theres no risk of overfilling a mag unless the mag is very cold and the bottle of propane is very warm, the temps and pressures will put an overfill of cold propane in ur mag which will expand and possibly rupture when it heats up, I've had this happen

but generally, under normal conditions, there is no "maximum" time to fill a mag, it simply stops filling when it is full

Sounds good to me. Filling in bursts though is important from what i've read? Like 8s with 3s in between?

Thanks for the response nooblord (love the name)

I've never bothered filling in bursts, but I can see the logic in it.

As propane decompresses from the liquid in the bottle, to gas as it enters your mag, it will decrease in temperature. Giving it a few seconds in between will allow the gas in your mag to warm back up before continuing to fill it with more "cold" gas.

Thus, it's a good way to prevent the mag from getting filled to the limit with cold gas, which then expands beyond the pressure limit as it warms up.

It's not a big deal, though.
