Just finished assembling my .375 Raptor AR10.

I love a thread that just won't die.
Curious about that 375 Raptor results myself.

D**N fine stable of thoroughbred rifles you have there. You sir have my envy.
Little off topic but still the AR platform.
Just used an Aero Precision M4E1 upper and lower to put together an 16" 556/223 Mid-length AR-15 for my sons HS graduation present.
I love Aero Precision and own several other Aero Precision based AR-15's.

I left the scope where it was at with my first 100 yard group and sent 3 rounds to the 200 yard line just to confirm my drop. Under half inch!!! I then zeroed the scope for 200 yards, which puts me 2 1/2" high at 100.

This particular rifle was a completely spontaneous deal.

I was talking to CH4D Tool and die on the phone and they were digging through a bunch of wildcat dies looking for a set of 6.5 Gibbs dies for me. While he was looking through the dies he was reading them out loud, he happen to say ".375 Raptor". I asked what that was. He said it was a .308 shortened and necked up to .375.

A week or so later I was in the reloading room and recalled the conversation. So I did a search for the .375 Raptor took a look at their web site and saw it was designed for the AR10! Seeing I am big into AR's especially wildcat AR's ( 6x45, 25x45, .243 LBC, 6x6.8 SPC, 6.5 PCC, 22x6.8 SPC Etc). The chambering caught my attention. Here in the Pacific Northwest, almost all my Elk and Bear shot in the timber have been shot at 70 yards or less. I have been hunting with a 6.5 Grendel but after some research on the .375 Raptor. I figured this would be about a Hammer of a gas gun in most of my timber hunting situations and a solid 300 yard chambering in the open.

I contacted X-Caliber barrels and they had a 18", stainless , 1-10 twist Raptor barrel on hand. I ordered it, called CH4D ordered the die set. Then got on line and ordered a bunch of the Lehigh 250gr Controlled Fracturing bullets and the rifle came together over a 3 to 4 week period as parts arrived and I found time to assemble it.

I was more than impressed with the first range results a guy couldn't ask for more than a 1/2 moa big bore AR10!

I have assembled many AR's and I really like this chambering and how well it shot right away.

I'm really looking forward to destroying some Rockchucks as soon as the weather breaks and starts to warm up!!!

Dayummm ! Nice shooting !
I've been researching this for a little over a year now...
That's one sweet rig !
Dies at this point would have to be custom.
Can't find much in stock at this point...
I guess I'll wait til someone gets bored and wants to unload one (see what I did there ?!)
