Lefties rejoice. KAK Industry just announced the new left-handed version of their K-SPEC Enhanced BCG for the AR-15. As a righty, I’m not always cognizant of the off-handed struggles with semi-autos. After shooting a bunch with a buddy this summer and seeing him get blasted in the face with brass, though, I’m learning. KAK’s K-SPEC Enhanced BCG’s have been getting good buzz with shooters, and now they’re available in a left handed option.
The K-SPEC Enhanced BCGs
KAK Industry released its enhanced Bolt Carrier Group (BCG) earlier this year. KAK has taken that design and reversed it for the left-handed shooter. It featured a downward gas vent to minimize blowback to the shooter’s face. The company relocated the two standard gas relief ports on a regular AR BCG from the ejection port side of the carrier to the bottom, in the magazine feed lip channels.
I saw some concern about crud being blown into the mag well and magazine with this method. KAK shows testing on its website, ensuring that wasn’t a problem, though. I’ve seen feedback on some of the various AR forums from folks using them, indicating this was not an issue.
In addition to the downward gas vents, the K-SPEC Enhanced BCG’s also have slotted angled carrier rails to help clear debris. They’re made to clear out sand, mud, dirt, and grime, including suppressor fouling. The KAK Industry K-SPEC bolts get the added bonus of dual ejectors for consistent ejection.
Now Available for the Lefties in Your Life
KAK took all of the features of the K-SPEC Enhanced BCGs and flipped them for lefties. The Left Hand BCGs are available in a Chrome Carrier with Phosphate Bolt version and a Chrome Lined Phosphate version. Both are currently offered with a 5.56/.300 BO bolt. KAK does offer other left-hand bolt options as well, though, and the left-hand K-SPEC bolt carriers are available separately.
The K-SPEC Enhanced BCGs work particularly well when shooting with a suppressor to mitigate the increased blowback. The downward venting also results in a quieter report as well. Response to these has been very positive. If you’re doing a new build, especially one that you intend to run suppressed, it’s well worth taking a look at the K-SPEC Enhanced BCGs in general.
If you’re a lefty, then the new left-handed BCG should absolutely be on your shortlist. Just remember to get a left-handed upper to go with it!
