Last time you saw it, it looked like the earlier configuration. A few parts have changed. Here is the rundown. The base is still an Aero Precision M4E1 receiver set. Minor swaps: dust cover, forward assist, receiver end plate, and the castle nut on the Law Tactical folder. All four came from Forward Controls Design, the same company I use for the ambidextrous magazine release and bolt catch. The larger change is the handguard. I replaced the Strike Industries rail with a Geissele. On it are a Ferro Concepts M-LOK QD sling point and, at the front on the bottom, a Noveske K9 barricade stop. It is aggressive. I like it, and I need it because I only have the spare arm. I put another K9 on the new 8.6 Blackout, this rifle’s larger sibling. The Scalarworks Peak irons that used to sit here in black are now the tan set, which has been hard to find. The black Peaks went on the 8.6. Both rifles are set up as SBRs. As it stands, the 300 Blackout is a two-stamp gun. When I have a .338 can for the 8.6, that one will be two-stamp as well. Because this 300 Blackout is an SBR, I went back to my preferred B5 Systems grip and stock. There is a Unity Tactical riser with a Vortex Razor UH-1 holographic sight. I still shoot this mostly on irons. The riser helps the sight picture with my one-arm hold and lifts the holosight over the irons when I do use it. I also removed the binary trigger. For me it is a poor fit. Keeping the rifle steady while working the trigger both ways is inaccurate with a one-handed hold. My trigger finger is fine on semi-auto. I expect this to be the finished 300 Blackout. There may be small add-ons later. I doubt it. Next I will take it to the range and show footage. I wanted this update out so you know what I am running. If you liked the video, give it a like. I will see you next time. #300Blackout #SBR #AR15 #RifleUpdate #Geissele #B5Systems #AeroPrecision #GunTube Mon, 09 Nov 2026 17:07:02 GMT https://validator.w3.org/feed/docs/rss2.html PeerTube - https://greyhive.com https://greyhive.com/lazy-static/avatars/5746210d-885d-44b2-9be0-92bf1e4d34df.webp https://greyhive.com/videos/watch/add64c88-8591-417f-af0c-309e342729d4 All rights reserved, unless otherwise specified in the terms specified at https://greyhive.com/about and potential licenses granted by each content's rightholder.
