"The finish is right on par with my other lowers. I have \"zero\" complaints. Jump on this deal asap. Lord knows how long they will be this price. I should have ordered about 2 more, instead of just 1. People complain about the horse logo. Stop it. It's a lower for an AR-15. Shut up and build. Fast shipping by CTD, also. Glad I live close to their warehouse. I got free shipping! I will be purchasing another one soon. Merica!"

"Picked up 4 of these lowers for projects in going to be working on.The BIG plus was that by shipping them to the local store there NO FFL fees or shipping cost, saving me at least $50.If you order online items at the store computer Kiosk, shipping is free if you have it delivered to the store."

"The price is insane, had to buy two. The finish is great, already assembled the first one and Bushmaster upper fit like a glove. CMMG lower kit went in smoothly. Not one complain, all smiles."

"Got the lower in after about 10 days, (7 of which kept saying \"processing in warehouse\", only took 2 days to arrive after they were shipped. Appears to be of good quality, great buy for the money though. I would consider buying from CTD again! Hope to start building my lowers in a few weeks, as money allows, hopefully I can update then on how well parts fit!!!"

"I ordered 3 of these at 59 shipped. DPMS and PSA parts kits both fit perfectly. I honestly cannot tell the difference between these and others costing double I have used in the past. Obviously I will use these when they are available. I have built about 10 rifles and if you take the roll stamp off of the lowers you cannot tell the difference. Don't pay more than you have to, just make sure they are MilSpec and go with the best deal."

"just received the lower today. looks like a excellent lower and you can't beat the price! Just ordered the cmmg lower parts kit to start putting this together. This lower in top notch."

"I am completely impressed! This lower is top notch in my book. CMMG lower parts kit fit perfect, all pins tight but not so tight they have to be reemed out. Finish is great although I'm not a huge fan of the horse on the side(minor detail and who cares really). Fit my palmetto state armory upper perfectly, no slop. Best of all the price is great for a budget build. You will not be disappointed."

"I wouldn't hesitate for even a moment to buy more parts from this manufacturer or from CTD. A word of advice for the people like me who don't read the fine print. You have to be 21yrs old to have a lower receiver transferred to you even though you can buy an AR completely assembled in a rifle configuration at 18."

"This lower seems to be the same quality as higher priced lowers. It was a great buy at the price. The LPK installation went without a hitch. Now I have a complete lower for less than many stripped lowers."

"Ive ordered four of these lowers over the last 8 months. Each has been flawless and once built, works perfectly. For the CtD prices, I cant imagine paying more for any other brand."

"I was a little worried about this lower because of the low price. However, it is precisely machined and well finished. I assembled it with a DPMS parts kit, had no issues. Tested it with two of my uppers, 100% good."

"Great fit and finish. Just a little more work and it will be complete. The only thing that I don't care for is the \"busy\" stamped area, of the logo etc. and \"AM-15\". But, I can live with it because it is a great part."

"this build is for a backup weapon, I like because they seem to match up well with most AR uppers.For me this is just a lower build, not a complete weapon.I have built more than 16 complete AR 15 rifles with different barrel lengths, all have been better than average shooters. No reason for me to look for anything else."

"The Anderson is an excellent lower. It went together easily, all components, from Rock River, fit perfectly. I matched it to a DPMS upper, fired 100 rounds and every feed and cycle was right on. I am currently finishing my second Anderson lower build. This piece is basic and all business."

"I bought this lower for my first AR build. CMMG parts kit fit perfect. Tapco buffer tube fit perfect. BCM mid-length upper fit perfect. Finished rifle looks fantastic. It has been 100% reliable."

"I have built more than one of these and once fitted they perform as well as any other. As far as snug fit to upper, some will some won't. M-16 wasn't intended for snug fit. I can't believe nobody mentions the pistol grip screw with kits other than Anderson. Anderson doesn't thread the hole all the way through, so a mil-spec grip screw will bottom out before grip is 100% secure. Use Anderson kit or Magpul and there is no issue. Trigger guard roll pin hole is always tight with these also."
