I have a brand new SEI M21A5 barrel for sale. SEI replaced this barrel with a medium heavy barrel.
The barrel is new... I never fired a single shot from the barrel, but SEI did test fire it.
Ron Smith will install the barrel on your Poly Tech receiver at no charge. You save $75.00.
You must pay for the GI bolt conversion and test firing at their range. You supply the bolt.
SEI will also replace my serial # that is stamped on the barrel with your serial #.
Specifications as seen on SEI's web site:
" M21A5 Standard Weight 1x10x4 Groove w/M118LR Chamber 22 Inch Chrome-moly Barrel.
Will shoot accurately with M80 Ball Ammo. M80HT heat treat is available at additional cost. "
This particular barrel already has M80HT. You save even more $.
$360.00 shipped CONUS
I have the same barrel on my M21A5/RRM and it is very accurate with Portuguese NATO surplus.
