Rt/pro Foregrip

[VIN 1]

Does anyone know why there is a
threaded hole on the bottom of the RT/PRO foregrip?

[Shirow]

I don't know, never had one. Is there one on the top? If so, I'd guess it's a gas through

Hi.
Yes its a gas through, just got an RT today, mines running a fore grip.

I would guess...

That it's a hold-over from the RT machining process. The RT is a gas-through grip. The Pro isn't, but it appears to have a fair number of parts in common. The foregrip is similar between the two. With that in mind, I think it was machined in the RT style, but without the gas-through hole.

Just a guess though, I hope one of the techs or someone with more knowledge will answer.
