ATRH Ubolt Magnum XL - Open Beta v1.0

@ArmThyRightHand 368.0MiB Released July 27, 2025, 5:37 PM 0.100LBC 0 Reposts
This UBolt lower is for the Bearcreek Arsenal BC8 300 Win Mag upper,
It uses the Phase 5 HexOne rifle length buffer tube from Redcon1 Tactical,
A standard heavy 308 buffer spring with a short 308 buffer to allow the complete travel of the larger bolt.
since the Hex0ne buffer tube is unique I made a custom printable Magpul PRS lite style stock for it.

BC8 mags are also extremely expensive, 100$ for a five round mag is retarded.
So I made my own, its shit but the largest version can hold roughly 8 rounds if you use something to hold the mag follower all the way down while loading it.
It’s fully printed and uses a mag spring from a Cetme C magazine.

Included in this open beta is the step files for the mag itself.
If you buy an upper different than 300win mag, please feel free to remix the mag for it and release it for others to use.
The lower should work with all of the bc8 uppers.
