No, buffer tube is TM spec thread. https://www.facebook.com/groups/954757591262527/

So, has anyone changed the inner barrel yet and what did you fit?

You sure he's running 144a, everyone I know so far is hitting around 310-325 on 144a, Green I have heard of 346-350+

Does anyone know yet what type of inner barrels will fit, I've heard suggestions that the WE M4 type inner barrels might fit and also what about recoil spring upgrades?

I have owned six Marui recoils now, finally have a 416 coming from the far east, I always recommend putting a 363mm inner barrel into the ones that come with shorter inners (SCAR L, SCAR H, CQB, 416), as I understand it the compression ratio is improved greatly by putting in the longer inner barrel, so a stock gun firing at 280-290fps will get a bump in the fps to around 315-325fps without doing anything else to the internals.

Also ordered from Airsoft Zone earlier this year, very helpful, extremely well packed and speedy service, just what you want really.
