Yeah the reason I got one was the same. I knew about the shooters design one before hand but everywhere I looked was out of stock so I dropped money on the G&G one only to find it was pants. Then a week later I spotted the SD one for £15 and had to have it.
I also purchased one of these under the illusion it was designed for the G19. However when it arrived despite what the box markings stated I found that the grooves for the recoil spring were designed for a G17 which I had a friend shape to the G19 ones. However like above I found the slide wouldn't cycle due to the tight fit on the inner barrel oring on the outer barrel.
Also the thread adapter isn't worth it in the end. Mine ended up getting stuck in the G&G SS80 suppressor I purchased to use with it.
In the end I ended up sourcing a Shooter Design threaded barrel and haven't look
Did you remove any flashing from the inside of the kit? As when I checked mine over the rear bolts of the side rails actually when turned down to far push flashing which messes with the slide but not only that the bolts themselves can cause issues if turned in to much.
Finally finished my backup gun
Probably going to change the buis for a full carry handle.
Basic pic till I can get outside to get a proper pic without being hassled
Rumour mill according to airsoft news the new ones are going to come with metal cnc'd hop units.
Also on a side note mine has been upgraded with an infected airsoft mosfet and modify smooth gearset. 18rps at 350fps on a eg1000 and 7.4v lipo.
This is airsoft most of us run around with unlicensed trademarks on our replicas
Also to keep on topic Fellows do you get any wobble on your CTR? A friend of mine is using a G&P buffer tube and his is wobbling like an old person without thier zimmer frame.
