Lambda 6.01 Precision Stainless Steel AEG Inner Barrel – 420mm
The Lambda 6.01mm Precision Inner Barrel is a stainless steel tight-bore barrel for AEG airsoft platforms, machined to a 6.01mm internal bore diameter. The tighter 6.01mm bore diameter vs standard 6.08–6.10mm factory alternatives reduces the gap between the BB and barrel wall, improving the consistency of BB guidance and reducing the deviation that accumulates across each shot. Stainless steel construction provides durability and corrosion resistance across extended use.
At 420mm, this barrel suits M4 and M16 length platforms and certain longer-configured SMGs. Inner barrel upgrade is typically one of the highest-impact modifications for improving AEG consistency — a 6.01mm precision barrel is the correct step for players who want improved range and tighter groups from an established AEG platform.
