SOLGW makes good parts and this is no exception. rifle buffer for an A2 build, weight feels balanced for full length rifle gas. running this with a sprinco blue spring and the impulse is dead flat
Sons of Liberty Gun Works rifle length buffer at 5.4 oz is the right weight for an A2 stock with 20 inch barrel. Inside weights dont rattle. Phosphate steel body wont show wear like aluminum. Fits any rifle length receiver extension.
