The Modify Air Seal Nozzle for AK47 or AK74s fits any brand Kalashnikov or SLR AEG, including G&G RK, Echo1 Red Star, and others. The o-ring seal provides increased efficiency in any AK type airsoft rifle.
This air nozzle replaces a leaky or inefficient original air nozzle on any airsoft AK. This part works best when paired with a Modify cylinder head for best performance. Replacing a leaky air nozzle can improve performance by 20-50fps.
Note: This is a standard size air nozzle, not a bore-up.
