Took the A1 out shooting this weekend. Ran like a champ and is fairly accurate. Looks like it was the crappy UTG rear sight that wasn't centered. The GG&G MAD sight I'm using now sighted in without it being way left. I was easily hitting a steel plate at 275 yds off hand, using the CompM2. Blowback was as bad outside as it was in the indoor range, still plan on getting a PRI gasbuster charging handle.
Decided to cutout the rest of the vents in the upper handguard and trimmed the large ears off the heat shield. Think it looks better and should help in cooling. If Wolf ever gets spare parts, I plan on buying a spare piston tube so I can drill holes inline with the vents to help divert the gas.
Here is a few pics and video from shooting this yesterday (don't mind my daughter yelling in the video)
