Always wanted a HK MP5. in December HK started importing there sp5 pistol so I went to my local dealer and ask if he could get one for me and how much, he told me $2300.00, after looking them up on gun broker they where going for $3500.00. so I told the dealer to order one for me. after about a month he said they are very hard to get because all the dealers where buying them up and asking much way too much for them, then he told me about PTR 9c copy of the MP5, made on HK machines with the help of HK. He got one in a day or two later and called me, it has roller lockup every thing the HK has plus a few other things like picatinny rail built in, no need to purchase a clamp on mounting device, 1/2x28 threaded barrel, tri lug, and being made in the US you can drop a class 3 trigger in. (that is if you have $35000.00 to buy one). $1740.00 out the door. I added the SB brace. took it out for the 1st time yesterday and it ran perfectly, they must have sighted it in at the factory because I hit everything I aimed at. tried with my rebel suppressor it still ran with no problems.
