I finally got around to installing the Arca Swiss spigot on my AT LE, I don't know why I waited so long lol. In all honesty it was because I thought it looked funny so I held off, but I am usually not so vain, function over form has always been my moto and I am glad that I finally put it on. Now the bipod stows rearward and tucks flush with the chassis, not to mention the advantages of a lower bore height, better leverage being further out and the much improved stability. I used a 5/16" punch to remove and reinstall the roll pins in the chassis, it's the perfect size for the job.
