Help me out with this malfunction

**dylank0723** · 04-22-20, 17:17

New triarc 11.5, using m193. Springco blue and H1
So it will Fire the chambered round, cycle, but fail to feed the next round. I get a full trigger press and click, just on empty chamber. Locks open on empty mag. Any ideas? Was thinking my buffer was too heavy, but I get consistent ejection at 3-3:30

Did you try more than one mag?

Try a standard carbine spring, which I found runs well in my 10.5 with an H2. The blue may be too much. From Sprinco's website:

"BLUE Spring": ENHANCED Power Buffer Spring, Offers improved performance with most non-suppressed 12.5"-14.5" SBR's, 16" DI Mid-Length BBLS, and all mid-length uppers with adjustable gas blocks. Best performance is usually achieved using buffers ranging from ST-2T, H2, DPMS Extra Heavy Buffer. Will run in 18"+ Length BBL RRA'S with ST-T2 Buffers. Color Coded BLUE. "

What is the gas port size on the barrel?

ETA: I see they offer barrels for suppressed use only, did you get one of those? IMHO that setup should run especially on M193.

What’s that exactly?

That’s kinda the way I’m leaning, also thinking about just switching everything over to the A5 system
