- 12.5" AR Performance 6.8SPC barrel, mid length gas, matching Superbolt
- SLR adjustable gas block
- BCM upper receiver
- ALG rail
- Toolcraft BCG
- BCM charging handle
This upper has about 300 rounds on it, 100% suppressed. It has not been a safe queen. When the barrel was brand new there were some minor issues with failure to extract. Those issues were resolved with a Flitz chamber polish. Aside from that everything is in fine working order. $Sold
