Anyone run into FTE stovepipe issues with the Phantom Pup?
I am running a FM-15 with a 16" barrel and Sylvan arms AGB on it.
Recently started to get stovepipes every few rounds.
I checked the extractor and the pin etc is intact.
Reaching out to FM about it they definitely indicated that it would only reliably work with their dedicated lower or the FM pic rail adapter.
How many rounds has this thing been through, what troubleshooting steps have you attempted, and how consistent is the malfunction? Does it happen with other magazines?
Somewhere in the ballpark of 500-800 rounds.
I stripped it cleaned it, checked for loose gas key, checked the gas block for alignment and being fully open, confirmed those are all good.
Checked springs and guide rod, those are good too.
Confirmed extractor pin was not broken, I did go ahead and swap the extractor with another FM one.
New extractor has really positive grab on the case, and flicks the round out well both handheld and cycling the action. Significantly harder to install due to spring pressure.
Have had a pretty wide range of mags through it, multiple pmag 30 and 20 round mags which are known good from other rifles.
