I bought a Seekins SAR because my AAC silencer specs said 1.5" OD and the SAR specs said 1.5" ID. The SAR also said 12" everywhere I looked, while other brands said 12.5". The can starts at 11.75", so I expected 1/4" overlap and thought some light sanding may be all that was needed.
I finally got my can this weekend after the long wait and found the QD button sticks out another 16th", which means I need at least 1&5/8" ID on the rail if it's going to overlap the can at all. I also noticed the SAR rails are actually 12.5" despite all their advertising saying 12.0". The rail would need to be no longer than 11.75" if there's no overlapping the can.
I'm looking for 2 options:
A) What is the lightest reputable rail on the market which has full length top and bottom rails and is </= 11.75" and at least 1.365" ID?
B) What is the lightest reputable line of rails on the market which have full length top and bottom rails and are >11.75" and at least 1.625" ID?
