For those that have added prommy barrels to tm recoils; what fps changes have you had and what length have you installed? Ta
Esoterick
I use 275mm which is just the recommended HK416 barrel on Eagle6. I think FPS was marginal but I tend to ignore the chrono readings
Spatch
Concur, fps increase I found to be marginal, creating a better airseal with replacement hop rubber and various tricks will raise it a bit, tried various barrel and rubber combos in recoils recently
