I'll admit I was initially a bit hesitant about making this purchase since it involved testing and learning a completely new product/skill set. From the very beginning, Greg made the entire experience smooth and stress-free. He patiently walked me through every step, answered all of my questions, and took the time to ensure I fully understood how everything worked. What really stood out was his willingness to go above and beyond--not just completing the sale, but genuinely making sure I felt confident and comfortable with my purchase. As a female shopper, he made some recommendations according to my size/stature/ability to conceal and guided me towards the perfect piece! That level of support and professionalism is rare and very much appreciated. If you're considering this type of purchase, I would absolutely recommend working with him. Outstanding service, clear guidance, and a truly positive experience from start to finish. A++++! read more

Greg at AR Piece Maker is the best. I have given them 95% of my business for years now. Ask him anything you want. All questions are welcomed and Greg is always happy to share his knowledge with you. I've gone to the 'big box stores' twice in 4 years and it's the worst. Get there before they open, stand in line, take a ticket, wait forever, and tons of people hanging out listing to your business. Greg beats their prices anyways by at least ten bucks. Greg does it all. Certification. Appointments. One on one experience. Private party transfers. Builds. Ammo. Accessories. Range days. read more

I've had such a great experience working with Greg at AR Piecemaker. He's incredibly knowledgeable and really takes the time to help you understand what you're buying instead of just pushing products. If there's something specific you're looking for, chances are he can find it or build it. He's especially talented when it comes to custom builds and really specializes in AR-15 style rifles. The craftsmanship and attention to detail are impressive, and he's always happy to explain the process. One thing I really appreciate is that he also carries and recommends options that work well for women. Not every shop does that, and it makes a big difference when someone understands that comfort, fit, and confidence matter. If you're looking for someone honest, knowledgeable, and passionate about what they do, AR Piecemaker is definitely worth checking out. read more

From the Business

Specialties

Welcome to AR Piece Maker, practical and friendly firearms sales for everyday people. I'm a federally licensed FFL 07 firearms manufacturer and retailer specializing in AR15s, with a background in mechanical engineering, retail management and over 15 years of hands-on experience. I believe buying and owning A firearm should feel informative, comfortable, and pressure free. My goal is to help first time buyers and responsible owners understand their options build confidence and make smart choices through clear, honest guidance. Appointment Only. Please call or text.

History

Established in 2020.

Established in 2020, the business grew out of more than 15 years of hands-on experience working on firearms, including gunsmithing and building AR-15 platforms. What started as a personal hobby quickly turned into a business when more and more people began asking for help with custom builds and guidance. From the beginning, the focus has never been just on making a sale, but on helping customers feel confident and informed. Each client is treated with a personalized, consultation-style approach—sitting down to discuss their needs, intended use, and design preferences rather than simply processing a transaction. I strongly believe a firearm is one of the most important purchases a person can make, and I take pride in giving every customer the time, attention, and service that reflects that responsibility. Through quality workmanship, trust, and strong word-of-mouth referrals, the business has grown into a respected and loyal customer-driven operation.

I explained to the lady at her desk next to the front door that I couldn't wait any longer because there's to many other places I could take my business to. She politely said, "that's ok, have a nice day". My feeling is that this family owned business with which seems like at least 10 employees (including office staff) have unfortunately lost all care and concern for new Customers. I gave the 2 stars because I also bought my gun there the month prior. But even then I never felt appreciated. The whole staff, they wander around doing their own thing and completely ignore walk-ins. Got a question, take a #. Never again will I return to this store and I would not recommend them to anyone.

After finishing the rounds I brought, I noticed my groupings were down and to the left. Since I had just installed a new optic, I thought it might not be zeroed correctly. On my way out, I decided to ask for some advice. Mike was extremely kind and took the time to ask a few questions to understand the issue. He then gave me about 36 rounds, told me to grab a new target, and said he'd meet me in a lane. Long story short, he spent 10-15 minutes helping to figure out the problem and got me shooting in the right direction ;) at no cost. I didn't expect that at all and couldn't be more grateful for his time. I also met Steven, the owner, who was just as friendly and took time to answer my questions about purchasing specific firearms. At no point did I feel like a burden. Thanks again for your time, I'll definitely be back, even with a 30-40 minute commute. It's worth it.

I didn't know you had to remove a lot of components and pretty much get to the bare head. Well, with his experience, he was able to close the valves and get a good clamp on it so he could get a clean cut on the head. He called me back in a couple of hours once it was done. From the decking process, lots of aluminum material gets into the nooks and crannies. I had to use an air compressor to remove most of the loose aluminum. I was able to install the cylinder head and now that car is running with no issues with leaking from the head gasket. Excellent work and a great price! I'd go back for more work to be done.

Fast forward to this instance where I have a batch of rotors that I needed to be turned down 1mm each side. Call him, describe what I'm needing and ask if he has a rough estimate on price. He asks me to text pictures, I jot down his number and then send him pictures shortly after. Gave him an hr or so and called him back to see if he received the pictures. Doesnt reallt acknowledge it and is pushy to have me bring them in and that he can do it. I'm about 25ish mins away, but he insists that he'll be late at the shop and that it's no problem. I bring in 1 rotor to see if he can still give me an estimate and he suggests he can help me bring in the rest of the rotors, about 10 in total. As we're bringing them in, I ask him again how much he's thinking it's going to be and he mentions $50 each. At this point, it's beyond the threshold in which the supplier was going to reimburse me for so I ask if I can just machine 2 rotors for now and figure out what can be done with the supplier. The next week rolls around and days go where I dont hear anything. I text him and no response for a day or 2. I call later the following week and he gives me a response like the rotors have been done and that he's been waiting on me. I ask him texting is the best method of communication since he originally asked me to text and he said text is good. I ask him if he's been receiving my texts in which he responds with affirmation. I go to pick up the rotors and come to find out that he only did a single rotor in which I ask when the other side would be done and he says in about 1-2 business days. I say that's fine and then mention that I'll leave that single rotor behind and grab the rest. He then mentions that if I in doing just 2 rotors, that the price would be $100 each. At this point, I'm no longer feeling like this is about money and get the impression that he's just a shady crook now trying to take advantage of people. I'm a little shocked at the pricing at this point and ended up just taking all the rotors back and paid him his $100 to machine a single rotor. Ended up having another shop do the for $20 each

I had an incredible experience with AR PIECE MAKER! Greg is extremely knowledgeable, super helpful, and answered all of my questions and concerns with patience and clarity. He's a genuinely cool guy who makes you feel completely at home from the moment you walk in. Working with Greg made the whole process smooth and enjoyable--unlike other places where asking a simple question can make you feel like a rookie. I completed my first transaction in December of 2025 it was a PPT. about two months later, i was back for more haha. I purchased a rifle--absolutely beautiful, I might add! What really sets AR PIECE MAKER apart is their commitment to backing every build 100%. Any issues? Just give Greg a call, and he'll make sure you're taken care of. That level of support truly built my confidence in AR PIECE MAKER. Overall, my experience here deserves 5 stars. Whether you're an experienced shooter or new to firearms, this is the place to learn, purchase, and gain valuable knowledge about firearm safety and more. I wholeheartedly recommend AR PIECE MAKER to anyone looking for quality builds and top-notch service. read more

I always recommend AR Piece Maker to everyone. Appointment only. No waiting around just to deal with an employee who is just there to do their hours. He has always been very easy to work with and he gives his honest expertise in what firearm or part you should or should not get. He will price match and sometimes beat big competitors so that you get a good deal. He's licensed to do actual gun smithing so he's my go to guy. He makes people new to firearms feel welcome and he will happily educate them. If he doesn't have it in stock, he can order it and usually gets it in fast. The ARs he builds are better and less expensive than the big name brands. I stopped buying from other places once I bought from him. read more

Greg is a good guy and knows his stuff. He is very patient and makes sure you get what you want. He won't push his choices on you. If he doesn't have it in stock he will order it for you. I have made several purchases from him and I've enjoyed each experience. I also sent a female friend to him for her first ever gun purchase. She took her test and Greg showed her several handgun options before she finally settled on one. She had initially felt nervous being a novice and a girl on top of it but Greg made her feel comfortable. She had lots of questions and Greg answered them all and she's already interested in her next purchase. Can't say enough good things. read more
