The stock's great, a really solid bit of kit. Feels much like the G&G M14 sturdiness. The gearbox is easy to put in - you need to install the supplied motor as the DMR stock requires a slight angle change in comparison to the stock M14. I'm not sure whether the G&G gearbox is entirely compatible, though.

Ghostx3, you're totally wrong. And whoever told you that M4s can't shoot 'far enough' for the sight is a tit.
The RCO was designed specifically for the M16A4 and the M4 - the new TA44 was made to fit in the carry handle of the M4.
As for your 'fibre-optics', you mean the chevron. It's a light intensifier, not a glowstick. Alot of pics I've seen of the Army has guys using the TA01; the USMC have their own 'custom' ACOG, the TA31RCO (Rifle Combat Optic).
Cheers bud. The gun's TOP so has the FN markings and all that. Inside, it's got a PGC gearbox and a 9.6 in the box mag wired to the trigger. The Mk 1 handguards are from a TOP Mk 1 model. As for the rail, it was designed and built by my brother. He'll probably do a run of them if there's enough interest.
