I'm Using M193 ammo the 10.5" MRP is having failure to extract/double feed problems, swapping it with a 14.5" barrel its aok. What seems to be the problem? I'm using a brand new LMT standard FA bolt, no O ring.

If the 14.5 runs good, I'd suggest that the 10.5 has a problem with the gas system causing preamture unlocking? I guess the thing to look for is ejection patterns? This is funny cause LMT is meant to ahve made its rep on the 10.5s.

Try the O-ring.

Try the O-ring or a Wolff extra-power extractor spring.

twl...he'd still be unlocking early no? The RRB and 0/D rings are trying to cure the symptomns and not he problem, overgassing leading to premature unlocking.

I would definitely get an able assistant, a video recorder and go down to the range and check ejection patterns and ejection port flash. If you are unlocking early (as I suspect you might be), it should actually be visible. I would then send a DVD copy of the video to LMT as aks them what they think and what they propose as a solution.
The MRP is meant to be the primo grade shiznit from LMT and it shouldn't malfunction liek that.

Heavy buffers delay bolt unlock not just slow the faster action from increased gas pressure.

The MRP is brand new. I will use an O ring or D fender on the bolt as well as a H buffer or RRB and see what happens. Thanks.
