M4 gear box / scar gear box

Recommended Posts

Right guys I'm going to be doing a hpa polar star jack install into a scar soon ( assuming that most the version2 gearboxs are relatively the same across the makes but it will most likely be on a G&G scar L ) just wanted to know any differences in the two gearboxes and external gearbox parts things like trigger unit , selector plate etc , they whole gear box is going to be stripped out anyway apart from trigger unit safety , Spring guide and that's about it off the top of my head ...

The G&G SCAR gearbox isn't a totally standard V2 box. The ambidextrous fire selector is driven by gears mounted on the outside and the nozzle is an odd length too. The hop unit is proprietary and is screwed in place. I recently fitted a BTC Spectre to mine and while it is broadly the same there are some ...special... tweaks as I say.

That sounds like making problems for the sake of it.

 

Stick with the G&G and deal with whatever that throws up.
