10.5” stainless 300 blackout barrel - TRYBE Defense AR-15 Barrel, .300 AAC Blackout

Amazing looking barrel. Shoots well. Had a slight issue where my Aero precision upper receiver feed ramps we’re slightly lower than the barrels feed ramps. Created a lip where the nose of the bullets would get stuck and not feed. Took a couple attempts with a dremmel and a grinding bit (think chainsaw sharpener dremmel bit style, small and cylindrical). It matched the radius well and allowed me to remove the barrel and gently work the entry point of the barrel feed ramp down. I’d Grind a tiny bit and reassemble, inspect and repeat until it was a smooth transition. Polished it with the dremmel. No harsh lip to catch the nose of the bullet, it glides into the chamber smooth as silk. Wasn’t a huge deal. Was more work that bolt and go but not sure if the upper or the barrel is to blame. Either way I think this is how stuff goes when building a custom gun with parts from many manufacturers. It worked out well and I’m pleased.
