I am wanting to up-grade my charging handle on my DPMS 308 LR RECON. I am trying to decide between Rainier Arms and BCM. Does anyone have any good or bad experience with either of these? I know the BCM can be ordered in small, medium, & large. I believe Rainier Arms only comes in one size. They both looked like they were made out of the same material. The main difference that I see is price. Any input would be appreciated. Thanks Justin
