The Armaspec Mid-Length Gas Tube (brand part no. ARM653-ML) is an 11.75-inch gas tube sized to run in a mid-length AR-15 gas system. It is a direct factory-length replacement, so it drops into a mid-length gas block and carrier key without the fitting or trimming that an incorrectly sized tube would require. Builders replacing a bent, pitted, or worn gas tube during an upper build or refresh get a clean, correctly dimensioned part rather than guessing at length. Armaspec builds the gas system parts it sells specifically for AR-platform rifles, and this tube is confirmed as an AR-15 accessory for that platform.
