Happy new year all, another update...
While looking at ways to reduce the weight of the 249 for the 2017 season I decided on two items with additional items to potentially come.
1. Removal of the forward upper rail, replacing it with a polymer barrel heat cover
2. Removal of the rear clamp from the ready mag battery compartment. If you're using a battery storage system similar to, or modeled after, my set up and would like to do this as well - it is not for the faint of heart.
2A. Here is the battery compartment as it sits now, referenced earlier in this thread as constructed from an ICS ready mag and modified ICS high cap mag.
2B. First, the ready mag needs to be removed from the stock, and the wires cut to allow full disassembly.
2C. I then used a cut off wheel/grinder to remove the first weld and then bending the frame back and forth multiple times broke the second weld. After cleaning up the welds with the grinder the ready mag only needed some sanding and paint.
2D. I then fed a bolt through the previously made holes for routing wires to ensure the alignment, located the mag where I wanted it and marked out common alignment points with a sharpie. I then used these points to make a grid on both the ready mag and stock to allow proper coordination of drilling locations for new bolts.
2E. After some trial and error I drilled four new holes, two in the stock, two in the ready mag. These were cleaned up with a file and primed/painted over. After this, two bolts were fed through and JB welded into place on the stock. Once cured, I marked the bolts, removed the nuts and ready mag, then took my cut off saw to the bolts in order to cut them down. I applied lock tight then painted over the threads to ensure the nuts would not back off.
2F. In order to fit the mag in properly, a small portion had to be notched to fit around the forward most nut and washer. After all adjustments were made, I desoldered the DEANS connectors and ran new wires, then soldered to the removed connectors.
I'm quite happy with this modification, and it brings it to my initial thoughts on how the mag would sit. Changing the orientation allows for no more flex (the clamp could slide around slightly), and the angle of the mag would cause the corner to dig into my wrist when in the high ready or holding the gun vertical in my right hand. The adjustment allows the mag to clear my wrist making it much more comfortable. The only downside is that the stock needs to be moved back one inch (one position) to allow the mag to clear the body and be removed, but this is quite minor.
Once the barrel heat cover arrives, both will be painted and integrated into the current camo.
