I would prefer we got some more feedback from consumers that have bought this firearm.
My personal experience has been very positive. I do own a 10/22 and have shot the GSG a couple of times but do not have a personal one. The fit and finish on the GSG 15 is great - I prefer the look and feel of the GSG 15 in this format compared to my 10/22 in the Archangel kit. Both firearms (10/22 and GSG 15) are picky when it comes to low power ammo - they don't cycle consistently. They (10/22 and GSG 15) also don't prefer lead bullets - they hang up on the feed ramp. Both of these problems are understandable and don't happen on every round.
One problem I have had with my 10/22 Archangel is the mag that came with the kit has already (2 years and about 1,000 rounds) started to come apart - a spring has come out of the top of the mag - but so far it still works.
I hope this has been helpful and would love to have others opinions.
