    This is a keeper

    This is my second AR pistol build. Had to wait 6 weeks for the custom shop that I bought the upper from to receive it. This upper is quality built – no tooling marks, good M-LOK furniture and excellent finish. Just finished the build with another OEM lower but have not had time to get to the range. The price was outstanding and I had the upper in less than a week. Smart shopping in my way of thinking.

    So when I started to do my AR build I did a research and there was a lot of bad chatter about these guys here at K&M Tactical but I’ll tell you this much they build a solid firearm got it 7 days after I ordered it made it into my lower and that’s all she wrote sweet music to my ears definitely will do another build with KM

    Really pleased with this upper, range was enjoyable and mostly for sighting in a new red dot. Ran 100%, very pleased with this product, Thanks again!

    Good budget upper for a great price. While all the other online retailers are taking advantage of the Covid/election situation and upping their prices, KM keeps theirs reasonable. Mated it with a poly 80% lower, great fit. Also am using a CMMG .22lr conversion BCG and that is shooting 3-4MOA which is, in my experience, excellent. When shooting .223/5.56 it goes about 2MOA with me which, again, is excellent. The MLOK handguard is solid and pleasant looking. This kicks out M193 at about 2 o’ clock which tells me the gas port is just about right. I get a little bit of barrel jump but that’s going to happen with carbine gas systems and a shockwave pistol brace that can’t give optimal pull distance. This is much better that the BCA uppers I’ve bought in the past.BCA has also upped their prices a solid 33-50%, are usually 4MOA, have blems and machine marks, and generally feels rough especially their BCGs. All around I couldn’t ask for a better budget upper. The only step up from this would be a BCM. and that would cost twice the price of this upper.

    Great product no issues at all with feed or ejecting . Very accurate and quality is better then most budget brands. I slapped it together with my Anderson Lower and she ran like champ . . I will be buying the 20″inch once I see it in stock !!
