I'm new to the AR10 platform. I recently bought a JP LRP-07 in 6.5 CM with a LRI-20 upper. I would like to add a .308 upper and was wondering if there were any cheaper options than JP? JP wants $2,300 base price. I didn't see that you can buy just the LRI-20 upper and build it myself or I would. Thanks in advance.
 
No there is not. The LRI-20 is a side charging rifle which has unique interface between the upper and lower where a traditional upper would normally have space for a charging handle making the LRP-07 lower used with the LRI-20 upper incompatible with anything else. They used to have a different LRP-07 lower for use with their non-side-charging LTC-19 uppers/rifles but those appear to have been discontinued as of earlier this year as they are not on the website anywhere.
