Will jp lrp fit a mars lower?

Also the JP LRP-07 lower is different than a regular DPMS pattern, it will only fit a LRP-07 upper because it doesnt have a rear charging handle.


That upper from JP should work on a SR-25 like your LMT lower.
 
Annnd... It only cost $1200 with a BCG, WTF. JP sure is proud of their shit!
Buy once cry once. I have several JP rifles, some with a bunch of JP parts, one complete factory rifle. All are the best shooting most accurate rifles I have. Also JP parts and complete builds hold their value over time.
