Quite often I get asked, “What do you mean when you say you blueprint and match bolts, extensions, and breech faces?”
The answer is actually simple: everything is machined and verified to be properly aligned with the bore’s centerline, perfectly perpendicular where it matters, and correctly spaced to ensure even load distribution.
Why does that matter?
It’s one of the reasons we don’t commonly see off-center case base bulges or bolt lug failures at the rates often associated with less refined systems. When the bolt, extension, and breech face are properly matched and trued, the load is distributed evenly across all locking lugs rather than concentrated on only a few.
The result is smoother lockup, more consistent engagement, and a system that is far less prone to binding—even when the extension area isn’t perfectly maintained.
The follow-up question is usually:
“Well, if I ever break a bolt, can I use another one?”
The video answers that question better than words can. However, Red A Plemons is the mastermind behind this methodology, I added a twist from what I did with T-Box but he is the one who started this all.
A perfectly trued and matched bolt, extension and breech gets you a consistent lock and unlock evenly distributed across all lugs at the same time.
