Re: 6.5 creedmore?
Good point Skyfish.
Although I'm not sure there is a huge weight difference between the large frame AR receiver sets (AR-10/LR-308) and a standard AR-15 receiver. Granted the barrel nut and a few other parts have to be up-sized to accommodate a 6.5 CM or .308 frame AR. But I'd be curious to see an apples to apples comparison all components being equal how much weight is added to go to a large frame receiver.
