Hi Guys!

I've now assembled two rifles. One is a Mega Billet Monolithic setup in 5.56mm (16"). The other is a Noveske forged upper / lower (18") in 6.8 SPC.

I am not having any problems with function at all. Still, I have a question concerning buffer weight. For both rifles I used the standard LMT carbine buffer... the cheapest one. This is the one part I went cheap on because I was not sure exactly which weight to choose. Since I am having absolutely no problems with the functioning of the rifles, would there be any reason any of you good folks would switch to a heavier buffer? I am using the heavy duty chrome silicon buffer spring from Larue Tactical if that makes a difference. Your thoughts on this would be greatly appreciated.
