Hey gang,
If anybody is interested I have a used (bought new, been sitting in safe, just fired 300 rounds today) Wolf A1 T91 16” upper with a VG6 Gamma & Aero Precision ambi charging handle, I also upgraded the extractor spring to a Tactical Springs 5 coil extra power spring and a Vton o-ring (the factory spring was bent when received). I’m asking $550 shipped. Payment could be PP F&F or Goods + 3.5%, MO or checks (please allow check to clear before shipping). If you have any question please feel free to ask.
Nothing wrong with the upper just not my thing. Worked well with standard buffer and spring.
