Description
The ACE inner barrel is supplied as an internal replacement part for the HPA AR/M4 airsoft rifle. It is the barrel itself rather than a complete upper or a whole gun, so it is relevant when you are repairing, upgrading or rebuilding an existing rifle and want to fit a fresh bore without replacing the entire assembly.
The listing carries a semi-only ETU marking, so compare that against the trigger unit and firing setup in your own rifle before ordering. Because internal components differ between models, check the details shown here against your gun rather than assuming a straight swap.
