USPreparing for “Lefty”
Great ! Functioned perfectly. No issue. Both bolt and upper were perfect match.
USNice fit and finish
Left handed parts are hard to find. This upper is a great value on a hard to find part. Bought it to build a left handed upper to use instructing left handed students and am quite happy with it.
USRecommend for lefties
Docking a star bc this products should be priced the same as the right handed version. No issues with quality. Great for lefties. I recommend...when on sale.
USGreat Option with one small problem
This was probably a unique situation but the Midwest Industries handguard I bought for this upper would not fit. This was due to the handguard having two tabs just below the picatinny rail that would normally protrude over the upper receiver. This isn't a problem with most mil-spec uppers. Unfortunately on this upper it is machined different than others. This upper would work with any handguard that mates up completely flat to the upper receiver (probably 90%+ of handgaurds). That being said, the fit and finish are great. I'm actually going to save this upper and do a .300BO pistol build instead. I'll just know to order a more normal handguard to mate with it on the next build. Thanks for providing this left-handed product for the small percentage of us out there who need this.
