KAK 416R Stainless steel 300 blackout barrel from Green Mountain barrel blank. 4.75" long, 1:7 twist, 5R rifling. .750 gas block journal, dimpled for gas block screws.

Comes assembled on an Axelson upper with Geiselle gas block and (proprietary length) gas tube. Assembled with chopped ALG forend and modified barrel nut.

Shoots well, prefers lighter subsonics (190's over 220's) and slings supers at surprising velocity. Has less than 200 rounds through it.

Note: this is not KAK's "economy" barrel, which has a slower twist and isn't stainless.

PP F&F preferred, or PP +3%. Price is shipped UPS, $175

No BCG, I'll throw in a charging handle though

Sold a barrel, USPS worker took it out of the package and resealed it. Selling this to refund the buyer. As such, I'll ship UPS or FEDEX, won't use USPS unless buyer insists.
