He is indeed correct. That gun is here on Oahu. Ashbash is where he is showing it again, MS? Cool.
Which reminds me...what do you get when an MP5A5 falls hopelessly in love with a G3-SAS?
My CQB gun an MP5-SAS named Grace:
Here she is all tight and ready to spring on her prey.
Here she is showing off the only battery small enough to fit in her...an 11.1v LiPo!
She is made from a TM MP5A5, a Wells R8 G3SAS and a few odds and ends from a Galaxy G5 and an JG MP5SD6. She sports internals from Systema, CA and TM (IIRC). I love her to death. She is small and quiet.
