When the Raptor Grach was announced, I asked my local shop to get me one in with an extra mag, mount etc. Ended up selling it back to them due it being awful. About three years later, walk in and see another one sitting on the counter with the current owner asking if the shop owner wanted to buy it back (They didn't).
I was chatting to the guy and he was explaining what was wrong with it, and I was responding to all the issues with "Mine did that too", only to then find out the guy had bought it from the shop owner 3 years ago! I offered him a reasonable amount for it, to which he accepted and so now one of the coolest (IMO) GBBP's is back in my collection! And yes, it's still barely useable... 😭
