Can't quite understand this one, but here's the situation...
First time firing my SBR, and also first time firing suppressed. Rifle is a Sig PM400 with 11.5" barrel, carbine gas, and fixed A2 FSP/gas block... stock everything except BCM receiver extension and spring with an upgraded H2 buffer and a BCM BCG with o-ring extractor upgrade. Original AR pistol was form 1'd and made into a SBR. Fires great without issues when not suppressed. Attach my QD YHM 7.62 Phantom LT, and first started firing with a nearly empty mag (about 6 rounds left). Immediately had FTE/double feeds (pushed the bullet back into the brass). Ditched the almost empty mag, made sure I didn't have any obstructions or other problems, and loaded a full mag. Fired great until I got down to about the same 6-7 rounds left, then experienced the same FTE/double feed malfunction. Ammo is factory AE .223 55gr FMJ, and mags were Magpul PMags.
Any advice or suggestions are greatly appreciated. Thanks ODTers!
