Ok, so I only had an hour to function test the lowers and try to zero...
Preface. My first time firing an AR or any rifle in a serious sense.
WOW!!!! What fun!
All shots were taken at an indoor AC'd range, from a bench except last round, off a stand(under the handguard), with irons only.(no batteries in the EOTECH anyhow).
I used the same 14.5 CL 1:7twist PSA upper on both of my lowers.
Lower 1- PSA, Gen2 LPK w/standard trigger.
Lower 2- CMMG, w/White Oak LPK/RRA 2stage trigger, BAD lever(I like the BAD)
First round is at 25yards and very first rounds are marked with pen. It also includes 3-4 function test rounds. This was off the PSA lower
Second Round off the PSA lower at 50yards
