Prometheus Flat Hop-up Tensioner

  • Model: PROM-FLAT
  • Shipping Weight: 0.01kgs
  • Manufactured by: Prometheus


Similar to the famous Firefly nubs, Prometheus Flat Hop Tensioner is a drop-in solution for flat-hop setups. This also works GREAT for R-hop setups in lieu the HS5 M-Nub or if you don't want to screw with your hop-arm but want to reap most of the benefits of your r-hopped barrel.

Just as in any flat-hop setup, users will need to flip their desired hop sleeve inside out, shave the mound off with a sharp blade (and possibly use some sandpaper to smooth out unwanted bits). For best results, also shave down the centering rib on the hop sleeve and rotate the sleeve such that the point that the BB will contact on the sleeve is the smooth unshaved part.

Pair with a Lonex Soft 50D hop-up rubber to achieve a good seal with little fuss.

Comes with both HARD and SOFT nubs for different FPS setups.
For increased hardness needed to lift heavy rounds in high-powered applications, insert a small pin in the hole on the nub.
