Also what scope is used on the middle rifle? What kind of groups you shoot with the three rifles at various distances?
Any real noticable difference in grouping when comparing barrel lengths?

John, some answers to your questions from top to bottom:
1: M14SE Crazy Horse® LITE SDM in TROY MCS (Norinco receiver)
22" standard weight 4 groove, 1:10 ROT Crazy Horse LITE barrel with M80HT.
New and unfired MOA or better is expected.
2: Crazy Horse® MK14 SEI in SAGE Mod 0 *medium heavy barrel (Poly Tech receiver)
18" medium heavy 4 groove, 1:10 ROT Crazy Horse barrel with M80HT.
The scope is a Burris 2-7x32 Handgun Scope with Ballistic Plex reticle.
This action shot sub-MOA with Portuguese surplus ball with an EOTech before I M80HT and Burris scope.
It is currently new and unfired, sub-MOA is expected.
3: MK14 SEI in SAGE Mod 1 (Norinco receiver) 18" 4 groove, 1:10 ROT chrome lined barrel. 25 round CMI magazine.
I have fired about 1800 rounds from this action and it will shoot 2 MOA all day and it will shoot better than 1 MOA with good ammo.
All three barrels have military M118LR chambers that allow me to shoot just about any 7.62/.308 ammo ever made.
M80HT is a heat treatment that allows unlined barrels to exceed chrome lined barrel life without sacrificing accuracy.
All three were custom built for me by Ron Smith at Smith Enterprise, Inc.
