I just took a bit of a deep dive into QPQ finish. And from what I can see, briley seems to be skipping the notch heat treat, and instead relying on QPQ finish (quench polish quench), which is a type of case hardening (I am only coming to this conclusion based on the info on their website) QPQ case harden depth ranges from 0.04mm - 0.45mm. And boasts a 60-70 Rockwell hardness from what I can see online. I am deciding to go with an actual heat treat on the notches, precise and repeatable technology via computer programming, which will give a case hardened depth 2-3x that of QPQ, of 1mm-1.5mm 55-60RC. For me, I value depth of the hardened case. when we are talking about anything above 55 RC it is all very hard. PVD finish I am going with has a hardness of 3300 HV. Which I am guessing is over 100RC. I can’t find a conversion table that goes that high.. this finish is only 3 microns thick. Those are the major differences when it comes to heat treat and surface finish.

I bought a lawn chair bag for carrying my M4. While traveling the bag doesn’t garner a second look in the backseat of the truck. At the end of the travel day, I grab the bag and walk back to the camper. Looks just like an RVer carrying their lawn chair! The zipper and the bag is plenty heavy duty and above all else does not scream ‘gun’.

I have a Benelli M4 but because of shoulder injuries I cannot fire from the shoulder; thus I fire from the hip. I presently have a Magpul Shooter’s, Rhodesian-style sling but it’s too short. I would appreciate any suggestions.

I don’t know too much about Their finish, but in my personal opinion, PVD is superior. as for the other aspects of it, not sure. All I know is that I have put extreme attention to detail in mine.. can’t speak for the others. They can’t touch my price point either, $138 USD. Got back from the machine shop today, finalizing the engraved stock positions..

I like it. Looks good!
