For the money it's a very good replica of the RC2 complete with the correct markings and muzzle device, just two niggles that prevents me giving 5 stars, one, the odd gold finish on the suppressors locking ring and two, the long shipping times, three or more weeks to get to me in the UK.

As usual shipping cost and time are manageable, price perfect and it was in perfect condition when I recieved it.
Installation was a breeze and it look outstanding, I love it, always happy to open my package from Sixmm, will be back to shop very very soon.
Have not shot through it yet but when I do I'll be sure to post updates on my next review.
