Have Questions About this Product?
Not perfect because there was a blemish on the threads (deep enough nick to show raw aluminum underneath). Acceptable because it'll be screwed into the lower and not visible.
My son and I bought the furniture kits for our AR's. Good quality, good price and it looks good.
Still in the process of building so I have not been able to test it out yet. Great price and fast shipping. We be back for some more needed parts.
I just installed buffer tube, have not shot gun yet, works great, great price
I recently purchased a mil-spec Magpul Furniture kit from AT3 Tactical and after I received it I realized that my buffer to was not mil-spec. I then contacted them with my problem and they sent me one out as a reasonable price with free shipping.
Excellent customer service and I definitely will be ordering more in the future.
