This is a great replacement for Scout rifles, a Scout-type gun build, or MK14 Navy, M39EMR/USMC weapon. Very accurate out to 900+ yards with good grade of ammo such as M118LR or U.S.N. MK316 ammo.

Regarding SEI barrel purchases
SEI barrels are short chambered! SEI recommends for barrel installation you use the services of a
QUALIFIED GUN SMITH – all our M14 barrels are short chambered, and require fitting to the receiver.
SEI uses a special-made Manson M118LR reamer, that allows accurate headspace for M118LR 175 gr. through M80 ball ammo. SEI barrels are not hard chromed in the bore!
