Buffer and spring change needed with .450?
Posted: Wed Dec 28, 2011 8:53 pm
Currently I have a standard carbine buffer spring but do have a Spikes powdered tungsten (ST1) buffer in the lower I have my 5.56 upper on. This is the lower I plan on using with the .450 upper, at least for now. Any problems with using this buffer and spring? Is the .450 BCG heavier than a 5.56 BCG?
If I decide on building a dedicated lower for the .450 is there a better buffer/spring set up?
