^this, when speaking with SF guys that have fielded the MSR for some time, and then showing them my SRS, they immediately show their displeasure of the MSR, and the appeal of the SRS (and the HTI). Granted, I have a slight bias. But I fell in love with the SRS the first time I pulled the trigger, and haven't looked back. All the other customs sit in the safe.If your looking for a modular system, the most cost effective is Desert Tech.
