Colt 639 SMG AR9 Lower Receiver - Reweld Listing ID: 3042046

This is a Colt 639 lower receiver that was rewelded by johnbrace from a de-milled SMG receiver. I have more photos showing the welding process as well. I cannot say that out all of the kinks have been worked out due to the stacking tolerances from the reweld, mag block, etc. However, I have made it through full mags before without issue. I just have not done enough testing to confidently say it will run 5,000+ rounds without a single hiccup. Also selling a brand new Colt 6450 upper that would pair with this very well (see my other listings).

Will consider all cash and trade offers.

Reach out with any other questions.
