Straight Pull AR15 Upper - Compatible with mil-spec lowers -

UPDATE 2.0 -----BIG CHANGES----- 3/10/26

This upper is not compatible with out of date builds! Charging handle is now connected to the bolt and this should've been the design the entire time, this allows for a much more comfortable and smooth bolt ride. There are now options for left and right handed shooters! Because i wanted the design to be mirrored perfectly, i had to raise the top picatinny rail to accomadate for the left handed bolt to not interfere with the cam path, thus keep note that the upper rail is slightly raised compared to the handguard rail. My new lower is the most reliable design yet. i noticed with a scope and bipod on a 16in rifle, that there is a lot of torque on the pistol grip screw if holding one handed, this created a weak spot in the lower design and also created a wiggle between the pistol grip and lower receiver. To fix this i included a very comfortable built in pistol grip eliminating the issue entirely. The down side to this is you will need a small set screw to install the safety spring and detent, thanks hoffman tactial for the idea. My stock/brace system has also been modified to be as strong as possible!.
