M4 SD Set Installation
 

I've just received the M4 SD set.. However it didn't come with a instruction
manuel while looking at the thing its kinda hard to think some part actuall fin in to the gun, and apperantly the inner barrel actually extend beyond the scilencer once I tried fitting it, Has anyone got any INstallation Experience with this thing? :sad: :sad:

Thanks
