THE IMAGE ABOVE IS A PAID ADVERTISEMENT
Greetings. I bought an A2 lower assy last month off the EE, and lucked up on a good used FN A2 upper about a week later off another forum. The FN barrel is stamped 1/7 twist, and also has FNMI as well as caliber. I've been away from ARs for about 25 years and have just got back into them. Are the FN A2 barrels chrome lined, or is it just the chamber or both?

Thanks.

If it is a in fact a government barrel (which it sounds like it is) it will be chrome lined.

That is a chrome lined barrel (both chamber and bore). I have a couple of the identical barrels. They are excellent barrels and VERY accurate. All the FN barrels I have had have shot better than any other military barrels I have had, Colt included. You have one of perhaps the best barrels produced for our military, congratulations....<><....:)

Thanks much for the info! I got a FN BCG and unnamed CH from GB, so I have finished this rifle, but haven't had a chance to take pics or shoot it yet.

As luck would have it, I got another lower from a local ARCOM member a couple of weeks ago and am now trying to build a mid length A2 carbine with collapsible stock.

BRD strikes again I guess.
