Special Weapons also manefactured MP5 look-a-likes that looked like the MP5 but did not share the HK's rotating bolt design.
What kind of laced weed are you smoking?
No roller locked HK ever had a "rotating bolt"....BECAUSE THEY WERE ROLLER LOCKED, DELAYED BLOWBACK!
I believe Special Weapons are NOT "look alikes", they are the real deal, of course with out HK markings. Vulcan/Hesse makes "look alikes" because I hear they use blowback operation instead of traditional HK delayed blowback operation.
I was at the casino the other day and went to the high rollers table. I asked the dealer 'what's the minimum bet?' He said, "a hundred dollars." I said what's the maximum? He said, "a box of .45"
