Keith R on Feb 4, 2019
Does anyone know if the buffer tube is milspec and can accept a different stock if decided to SBR or different pistol brace?
Donald S on Feb 4, 2019
BEST ANSWER: The SBA3 is a pistol brace designed to be on a mil-spec carbine buffer tube. So yes, this will work if you fill out a stamp. How ever, with the short turn around of E-file stamps (one month or so), I would get the lower and fill out the stamp paperwork, than build as a rifle if that is your intent.

Great price and quality.
Amazing price and great quality. I used a standard stripped fire/safe lower from PSA to keep it a matching build. The finish was perfect on all the parts I received. Flash can gives it a nice look.

Incredible value. Quality of materials is first rate. Fit and finish is excellent. What I received is flawless. Packaged carefully and shipped quickly. I would definitely recommend to a friend, or anyone for that matter. I'll probably get another, assuming they can keep them in stock long enough.

Good, but trigger is heavy
Received the kit yesterday. Took some time to ship out, but not too bad. Put it together and everything is good. The trigger is heavy. Haven't checked it yet, but I wouldn't be surprised if it's around 8 lbs. The reset is pretty loud and clunky. Not a deal killer, since I wasn't planning on keeping this trigger long, but it is a disappointing trigger.

My first impression is disappointment.
Received this today, upon inspection found shiny tool marks on bottom of flash can, also flash can is NOT centered inside the rail. When handling, the side of the flash can contacts the end of the rail creating this annoying noise as though something is loose. Inspected barrel and found no stamping or any identifying information as to what caliber this is. At this point I'm disappointed, if this was sold as a BLEM I could be more understanding, however I definitely was expecting better quality. I will update this review as I progress with the build.
