CMT, LMT.
Probably others, but these are all good stuff. If you are buying a ramped barrel extension or receiver, there's a real good chance it came from one of those companies, no matter whose name in on the packaging or engraved on the part. I can make you any kind of barrel/upper you want using an LMT M4 extension and LMT or CMT receiver. |

From the pictures I have seen, Armalite has extended feedramps, but they do NOT match up with M4 size extended feedramps. They appear to have their own thing going... CMT makes the Colt receivers and extensions. Not sure who makes the Armalites. |

I have used two Armalite uppers to build SPRs using Krieger barrels with M4 feedramps cut by Frank White of Compass Lake. The matched great. I admit this is a small test sample, but im batting 1000% so far.
