Vltor 5.3 oz a5 buffer weight - VLTOR A5 Specialty Buffer

I am changing my 18" spr build to a b5 collapsible stock from a standard a2 rifle stock and needed a buffer with similar weight to a rifle length weight. Combined with a voltr a5 receiver extension and the stock rifle spring i was able to achieve the transformation without loss of reliability . Optics planet had what i needed at the best price i could find. And their shipping time has improved drastically. They always seem to have what i need at the best price,and the shipping is free .
