Favorite lowers

[Ck867]

I only have experience with NFA lowers and it seems to work just fine.

I do not have any JP internals.  I have the QC receiver set.  Just starting to put things together.  

 

I was just throwing out some ideas for the OP since it seems like he wants the JP but can’t get it due to his state.  

 

Thank you you for all the advise, I’ll start with the hiperfire trigger.  Just add a part a month or so.

Jones arms makes a rock solid lower.  their Kronos AR9 is a beast and eats everything.

For the OP, I really like my QC10 lower.  Hiperfire 24C trigger in mine and an MBX buffer system.  For small parts, any decent quality parts will do.

Black Creek Precision.  I have, and really like, their Colt pattern upper.  If I were in the market for a Glock lower, theirs looks nice as well.

OP, The GMR-13 mag release is relatively easy to fix using an Odin Works mag release extension.

 

Do you have .stl model for this Maxwell,please?

Do you think that this extended mag release will fit? https://www.odinworks.com/XMGR2_p/acc-xgmr2.htm

I still have the magwell shown but replaced it with a Techwell.  I don't know about the Odin Works mag release.

FM-9 lower has been awesome! Installed a 3.5 .b CMC trigger and it's been a great choice.

Check out Tennessee Arms for their polymer lowers.  They have a video with a lower on a full auto and fire like 12000 round thru it...and they have a fully assembled kit...I have two PCC built on their lower and both  work reliably but took some tuning to get there.  They are probably one of the least expensive lowers around.  The only real problem I have had is fitting the lower and upper-they tend to go together very tightly so need to fit them.
