Was hoping someone could tell me if I am on the right track here.  I've been reading, looking at different products, sort of picked out a hypothetical parts list.  I am intrigued by the idea of a Glock mag lower.  Considering that, is there anything wrong with the following approach?

Quarter Circle GSF/Glock mag lower
Quarter Circle Glock-cut bolt
CMMG PDW Upper
Colt 9MM buffer (5.5 oz) & Wolff spring
hammer?

My specific questions:

No issues with QC bolt in CMMG upper?  

Hammer - I kind of got turned around reading through the various styles of AR hammers that will and won't work with 9MM bolts.  (or styles that will wear/damage over time)  Is there a bottom line answer as to which hammer will or won't function in the above configuration?  Will an M16 hammer work?  (on my M16, in full auto)

Thank you for the help!

I'm using a standard ar hammer.  The one with the ALG trigger group.  The bolt has to be ramped like a standard ar bolt carrier.

May want to try a slightly heavier buffer.

8.5oz seems popular  Spikes ST-9X or HeavyBuffer Q

I'll look at those.  I will be shooting suppressed, as well.
