Greetings,
I'd been intending to post a follow up regarding the new LRBHO lever from QC10. I have an early DDLES SFG lower that I was never able to get the last round hold open to work reliably, regardless of the adjustments I did to it. Found a post here about the new design, ordered and installed. Near 100% function so far, at least 500 or so rounds since the swap. Significant improvement in design. Check it out if you've not been able to get the original version to work. FWIW, I have a ramped bolt and a Geislee SSA/E FCG. Good luck to everyone.
Regards, Jim
