Gentlemen. Took this on a trade, but decided to build instead Early MRE m6a3 upper. Used. 14.7 nitrided/chf/6.8spcII Bore looks great. Stiff front sight(no play) This appears to be an early version. In addition to the early two piece carrier, it has some odd features. Pros/cons depending. 1st, it has a stepped barrel with 1/2 28 threading. Honestly, the upper feels less front heavy than I remember my other m6a3 being. Can include the SF brake shown for an additional fee. 2nd, the FSGB is pinned with roll pins. Not the usual impossible to remove factory pinning that dissuades lowly gunners from HG swaps. It may be a good candidate for a rail swap. Exterior is worn. It has a number "13" eched into the receiver. No dents or dings, so cerakote may be a decent option. Or, run as is, because **** show cars. Could be a cheap upper to build around. Looking for 800 shipped in the conn us. Please PM or email any questions. Happy to answer to the best of my ability. Plenty of feedback around. over a decade in the comm.
