A buddy and I designed this improvement over the Geissele reaction block.

Oftentimes, when you are tightening the castle nut, the receiver will rotate and you end up with a receiver extension/stock that isn’t aligned with the receiver. This block guarantees that they stay in perfect alignment at all times.View attachment 3558652View attachment 3558653View attachment 3558654View attachment 3558655
Yes!!! Take my money. About a year ago I made a wooden jig to work in addition to the Geissele Reaction Block and it was ok but this is great! Definitely interested in purchasing one if/when a production run happens!
 
Nice! I created a "clock block" a few years ago, but it relied on a Reaction Block. This is an all-in-one. Nice.

That’s where I started. I was originally looking at doing a modification for the Geissele reaction block, then decided I didn’t want to help them sell anything of theirs.
