The never-ending saga of my precision big bore rifle build may finally be coming to an end, thanks in large part to Billy Goat Machine, haha!!
I shipped off my beloved BAT EX action, 36" Bartlein 50 barrel, 36" Krieger 375 barrel, two bolts, two muzzle brakes, two reamers, and four GO/NO GO gauges to BGM a couple of months ago.
Just got the parts back today...my goodness, what beautiful machining!! So looking forward to getting this rig out to the range.
When that will be is anyone's guess, haha!! I'm recovering from left shoulder surgery, I'm left handed, so we'll see what my surgeon has to say. He said no running, swimming, or biking for about 3 months but I didn't hear anything about shooting a .510 DTC, haha!!
I've got a S&B PMII floating around here somewhere, I'm hoping it will do the trick with this rig. BAT EX came with a 20MOA rail. I still have to source rings or a 1-piece mount (more $$$, haha!!).
Anyway...the obligatory pics!!
First one is the BAT EX with the 50 cal barrel and Armalite MB attached. For reference, that's a lightweight hunting rifle with a 19" barrel behind it (photo courtesy of BGM!!)

Here's a close-up of the MB threading on the 375, along with a shot of the APA XXX Bastard II MB. Many, many thanks to BGM for pulling some strings and getting me this MB in my lifetime, haha!! For reference, the muzzle OD is 1.5"


Here's a close-up of the chamber end of the 375 barrel. For reference, the chamber end OD is 1.75"

Since this is a switch barrel setup, I had BGM punch witness marks in the barrels and action. I figured it might make barrel swaps easier.


And finally, a close up of the 510 barrel with the Armalite MB. For reference, the muzzle OD is 2". The last pic represents my remaining total net worth after paying for all this crap, haha!!
