The serrations on this mainspring housing help get the weight in the right place and gives you good traction.

Pump The Brakes

I bought this mainspring housing with the express intention of replacing the factory housing on my 2018-production Colt Mk IV Series 70. This housing’s machining and finish are fantastic, but it ended up being ANYTHING but a drop-in part. Have plenty of indicator fluid and a precision 90 file on hand, because there’s LOTS of work to do.
