I'm going to let Wally tell you about this beauty, and showcase some of the extras.
Since I know you and your readers sure love the Friday installments, I wanted to be sure to share my latest build. I wanted to end up with a lightweight, compact, and robust firearm, and had a few new suppliers whose parts I wanted to evaluate. Things have been really chaotic around the shop lately, but given enough free moments - usually at no more than 5 at any sitting – this was slow to come together.
It is a featherweight AR in .300 Blackout. It weighs in at 5.2lbs empty, plus another 0.9lbs for the titanium silencer.
The heart is the receiver – here it is a custom lower, a York Arms, of course. It is sporting recessed windows on the magwell to shed a little weight and to add some distinction.
I tried out some new engraving methods on receiver too.
Inside the receiver sits a York Arms custom two-stage trigger set right at 5 pounds. The windowed magwell also gives the opportunity to show off some magazines too. I used a diamond plate finish (Hydrodip, available through York!) on the magazine shown above.
The upper receiver is treated in electroless Nickel-Boron (you guessed it, we can do it for you) to give it a very hard, slick surface. The outside of the upper receiver was cerakoted black, but the inside retains its slick, silvery luster. Nickel Boron coating was also used on the bolt carrier, the bolt, cam pin, firing pin, and barrel extension. Having used Nickel Boron parts in a few other builds, I have been really delighted with how smooth they glide and how easily they wipe clean.
For the barrel, the intent was to go accurate and light. Off to the lathe to turn one – Match grade, air gaged, 1:8 stainless barrel chambered in 300 Blackout. It is a brief 9.75", has an ultralight profile and threaded muzzle.
I'll be the first to admit it may not be for everybody, but I am delighted with the SBR and am really looking forward to getting some time with it on the range. Of course at this rate, that may be a while!
Damn, but that is one beautiful AR, Wally - thanks for sharing!
That is all.
