rifle length spring for a 20 inch build, aero quality is what you expect at the price. spring tension is consistent across the length, no wonky coils. pairs with a rifle buffer for a smooth full length gas impulse
Aeros rifle length buffer spring works correctly in an A2 stock setup. Coil count and free length match milspec dimensions. Wish it came with a better price tag because the same dimensions in a basic stainless spring run half as much elsewhere.
