Yesterday I got my CTR and tall scope mounts so did some tweaking... So here they are all decked out for Spring: Daniel Defense/S&W with CTR left Dan Wesson with CTR right (needs more thought on the sling...) ArmaLite M15A4 with Nikon 3-9x40 left ArmaLite M15A4 with Nikon 3-9x40 right ETA: And here's the parts list for both AR builds: (CTR , scope and Vltor/BCM Gunfighter Model 4 charging handle not added yet) Also I need to doublecheck my math but it's interesting the ArmaLite and Daniel Defense builds came in at almost the same price. Of course there's lots of duplication.
