My favorite upper in my collection!!!

This upper is super lightweight yet solid. The key mod forearm is fantastic, it fits my hand better than any of my other rifles. Plus, it looks awesome!! I'll buy from SpecOps from now on!!

This One's for the owner

I just have to say I am completely satisfied with the owner of this company. I have been dealing with him for 6 weeks on a order of mine and he has handled it very well. Very nice guy to carry a conversation with and is a very well respected businessman. I love the way he runs his business and handles issues and have to say I will be recommending you to my buddy's who are planning on buying a ar-15. I myself will be ordering another upper from this company very soon. As always. Best regards.

Great Upper, Not your normal Budget Rifle

Upper came in a little late, lead time was 2-4 weeks, It got to me by the end of week 4. I will have to say it is worth the wait. Fit like a glove on my Ruger lower. Went to the ranger over the holiday week and it shop amazing. Tight groups! Quality was great. Extremely happy with my purchase. Will be buying again! Thanks SpecOp

Great Product!!

Ordered stripped upper for a S&W build on a promo sale in hopes of finding the perfect upper for my build. Received upper very well packaged and in perfect condition. Installed with my S&W BCG and charging handle and went straight to sighting in with my 3-12x44. Upper performs as good, if not better than my original upper and hasn't given me a bit of trouble. Looks great, runs great, and great company to deal with if you have any questions! Definitely will be purchasing from SpecOp in the future!

Great Upper, Budget 3-Gun Rifle

I used one of these ultralight uppers on a 3 gun build. I wanted a budget gun that I could try 3 gun with and not go full in with a competition gun. This is a great upper and it was much more economical than buying all the tools and paying retail prices for the components. I have about 50 rounds through it so far and it is proving to be very accurate and is soft shooting. The rifle is not over-gassed like most AR's tend to be. The BCG I selected has rather stiff gas rings and it wouldn't even lock back on an empty mag until after 40 or so rounds when the rings started to break in. I was thinking about an adjustable gas block but I don't think I need it. The hand guard is great, it's about as low profile as you can get and vents well, it doesn't heat up much. My upper is built on an Anchor Harvey upper and is very good fit and finish. The rest of the gun is pick-a-part: Anderson Lower, Seekins Safety/Bolt Release, PSA BCG and Buffer set, MFT minimalist stock, CMC Flat Trigger & Strike Industries Charging Handle. Complete gun is just over 5 LBS
