I've fired a bunch of 5.56 tracer and it was a lot of fun. The low cost of rimfire would make this a guaranteed chuckle. Clean the barrel well when done.
They sent me a 30 round replacement. The 2 rounder is for the German market only says ATI. For hunting purposes we hypothesized. The 2 rounder can be converted be removing the filler panels on the sides and replacing the spring and base. You can see the 2 round magazine in this photo.
The only problem with my GSG AK was the magazine. I was supplied a 2 shot instead of 30 shot magazine. Go figure? ATI promptly rectified the problem without complaint and allowed me to keep the 2 rounder.
What? No guitars to match the AR-10s? I also have one of the CAI L1A1 SLRs w/thumbhole stock. Mine likes to hang up while chambering on a regular basis. Have to "kick start" it to clear. Don't think much of CAI. Nice collection and photos.
Sold my Chiappa 1911-22 today via the interweb. I don't often sell personal firearms but this one was a real stinker IMO. A lot of folks on line seem to like them. I have to believe they and I have a different set of acceptable standards. I lost money on it. Live and learn.
