I ordered a Blackhole Weaponry back in November, took a little over 3 months to receive because of the holidays. Took about another month to acquire the rest of the parts. Used a Bear Creek Aresenal side charging upper that’s was on sale for cheap! Currently using an ALG EMR V2 M-lok that I had to slightly modify to fit over the BCA upper. May change that later on. Also using my grandfathered MI pistol lower. So if I do choose, I can carry it same as a handgun. Have no intention of doing so, but nice to have the option. Lol. Still need to get a couple scopes for this and my other rifles, so it will be borrowing for the time being.
Here’s a pic next to my 20” BHW.
