Just got a RRA Tac Entry.  It's supposed to have the Chromed Lined barrel.  How can I tell if it has it?  I see no markings.  Is the bore more shinny than a non chromed barrel?

Several ways come to mind:
1.  Verify configuration on the check list oon the end of the white RRA box
2.  Check for chrome-wash out at the muzzle (gray/silver "haze")
3.  Check the area of the bbl immediately over the chamber...if new, it will have a bbl number that corresponds with one of our chrome-lined numbers, or if older, it should have a three number/letter code, of which the third  character shouls be a "C"..N9C which is NATO chamber, 1:9 teist, and chrome lined.
Thanks.

My barrel has a "212" on it above the chamber.  What kind of barrel is it?

Steve,

The barrel is stamped with the number "204" It's a brand new barrel however. The box on the "Options" line has a hand written "CL" which I assume must mean chrome Lined?  In looking at the crown of the muzzel it does have a very thin grey/silver line around the tip of the crown.  

Kind of curious if you can confirm that it is chrome lined???

GS1000SN:  Your 212 is an AR0212 barrel....mid-length, chrome-lined, 1:9, NATO chamber.
Jay:  Your 204 is an AR0204 barrel...CAR-length, R4 profile, chrome-lined, NATO chamber.
Hope that helps.

Here's a picture of the muzzle of a chrome-lined RRA Entry Tactical:



The red arrow points to the silvery-gray chrome-wash that Steve mentioned.

By the way, this rifle was purchased during the ban, so the "flash hider" is actually RRA's press-on fake flash hider.  I'm not sure if RRA still sells rifles configured with this fake flash hider for perma-ban states.
