    Function over form

    I bought this buffer tube/stock kit to complete a budget lower. For the $29 I spent, I'm happy. It has some rough edges but it went together perfectly on my Anderson lower with UnbrandedAR LPK. This is the lowest price for an m4 style stock kit that I found.

    The stock that is included is a basic m4 style. It is a bit rougher than Magpul or other fancier stock manufacturers. That wasn't a big deal to me, it's what I expected, but it's something to note.

    I function checked the completed lower using a known good upper and it worked perfectly. I have not yet fired live ammo through it, but I expect it will cycle properly when I do. The buffer spring and buffer I received are proper spec for an AR15 carbine tube.

    Shipping did take a bit longer than expected (about 12 days from order to my door). That wasn't a huge deal to me since I am just slowly piecing together a budget build.

    When i saw the price I thought this was a blemish sale price. When the package arrived I checked it out thoroughly no blemishes. Now I have quality parts for my next build at an unbelievable price.
