LMT or JP BCG for a 6.5C semi?

[towerofpower93]

About to set up another AR10 upper for my MATEN lower. Need to get a BCG and am ignorant as to the go-to nowadays.

Plan is a 22-24" 6.5C barrel with +2" rifle gas and an AGB.

Have a buddy with a complete JP rifle in 6.5C which started with their LMOS system but he has since put in the full weight carrier and high pressure bolt.

Was planning to go the JP route, but hearing many good things about LMT's FA BCG with the HP bolt sporting dual ejectors.

I also have a $150 off gift certificate from JP I got off a prize table last year, so

So, any advice/experience is welcome as I start putting pieces together.

Thanks

If you run suppressed, go with either the full mass (FMOS) or variable mass (VMOS). If you're building a gun for PRS style matches go with the low mass (LMOS). Use a HP bolt in all carriers and pair it with a H2 308 silent captured spring.

Planning to run suppressed 100% of the time so figured the full mass carriers would be my go-to regardless of manufacturer.

Should you decide to go with an LMT BCG, they are hard to find in stock.

That said, Valhalla Tactical Supply shows to have the both the full auto version and semi-auto version in stock.

That’s where I found them earlier.

If you go the LMT route grab it they're hard to find most of the time.

What would be the benifit of the LMT FA carrier over the SA carrier?

I have run the JP on AR-10 builds and it performs flawlessly.

The full-auto carrier is slightly heavier. This could be an advantage if you need more mass.

That was my reasoning. More mass.
