Anybody know who sells uppers with 20" chrome lined barrels?All I see is 16". TIA,Nick

What twist rate are you looking for 1/9 or 1/7 and what profile, Gov't, etc.?


DSG Arms have 20" Gov't Armalite and Cavalry arms uppers and also CMMG have their own upper.

Talon Arms sells Sabre Defence 20" chrome lined barrels with M4 ramps barrel extensions, but I don't see any built uppers, maybe you could ask them to build an upper for you.

There might be other brands that other members will post here.

Thanks Alpha, I'll check them out.

Do you know if the CMMG 20" Govt 1:7 barrels are chrome lined? Anybody have any experience with them?

I was looking at their upper for my M16A4 clone build coming up.

Yes, the CMMG 20" Gov't 1/7 barrels are chrome lined chamber and bore per the description of their website.

Their info also showed that it have a M4 feed ramps barrel extension, so you should get a M4 type flat top upper receiver to match it.

I'm sorry I have no experience with any CMMG barrels.

Here's a link to CMMG's website, just click to enter their site and click on the barrels link when you are inside their shopping site (look at the bottom of the barrels webpage).
