I came in for an FFL transfer that was sent in and they took care of me promptly. The staff were great to talk to and spun up great conversations with them. I'll definitely be coming back here and using this as my default FFL. great customer service! read more

I have been to many gunsmith over the decades. This one's knowledge is by far the most important have delt with. I have had very minor work done to several, and heavy work to 2 different guns. One of them was turning a G19 into a G19C (ported barrel and slide), trigger work, undercuts and more. I have ran about 5k rounds through that one without a hiccup. Runs like a cheat code lol. Good pricing to. Huge selection of private party transfer guns on consignment to select from also. Bought a few of them over the last 2 years also. I drive 45 mins to go to them because of the service and knowledge. read more

Highly recommend coming here to get your guns cleaned! Best pricing in the area and quick turnaround time! I had dropped off two guns for cleaning and got it back within 10 business days and my, oh my, do they both look beautiful- and lubed up too! No one likes a dry gun. Thank you for your servicing Ron! read more

I had a really disappointing experience with this gunsmith. They originally told me it would take a couple of weeks, but it ended up taking a month and two weeks. I needed them to Cerakote the slide, cut a notch in my grip module for the safety fit, add a trigger, and switch the mag release from the left side to the right. The communication was awful--multiple times I was told different pick-up dates, and they kept pushing it back without any clear updates. On top of that, they lied about the status of my firearm. They told me it was basically done, just needed to be put back together. But when I came in, they were still working on cutting the grip--so it actually wasn't close to being done at all. The lack of transparency was really upsetting. However, I will say, the only reason I'm not giving this a one-star review is that the gun actually came out really well--the Cerakote was nice, and the cutting done to my grip was done very well. read more

I recently visited The Heavy Machine Gun Store, and I was very impressed with their professional services and knowledge. I felt very welcome and was treated with great respect and understanding of my situation. I learned a lot about what I can and cannot do. I spoke to Reza, the owner, who was very helpful, as was his staff. I highly recommend this FFL store. I've visited many other FFL stores and have often received incorrect information and poor treatment regarding my firearms. read more

A top notch firearm repair and sales business. Friendly knowledgeable staff. A small business who really cares and supports the community.

I came in to get my night sights installed on both my Glock 19 and 17. Reza did an incredible job overall on both! In general everyone within the store is super personable, professional and chill. They have my business moving forward and I will be recommending this place to my friends. Highly recommend! read more

Came here to swap my Glock 19 iron sights to Trijicon iron sights. They took 1 month to do this minuscule job, and did it poorly. The front sight came loose within the first 20 rounds at the range, and the rear sights were not centered. Took it back and the guy just screwed the front sight back on without even looking at it so it was crooked again. Took it to another shop to get the front and rear sights centered, and they did it perfectly within 5 minutes. Very disappointing experience. read more

everyone here was professional, and the staff was very good. The massage was excellent.

Capable gunsmith but doesn't meet commitments in terms of completing the work you pay for on a timely basis. Frustrating at a minimum when you have plans for weekend shooting when a firm delivery date is established. Missed two deadlines. read more

First time there. Very impressive gun store. Lots of inventory and really nice people to deal with. Competitive pricing and a great gunsmith on the premises read more

Just moved down to OC and needed to look for a new gunsmith. Did a quick yelp search and this shop had 5 stars. Went down to their shop and Corey was there and assisted me. I gave him my Glock 19 to install some parts and I couldn't be happier. Super professional and friendly. I will be coming back here since I trust Corey's expertise and will rely on him for any future gunsmithing needs. Don't hesitate to go here! They sell firearms as well. Stippling, cerokote, repairs, optic cuts, etc. I just know I will be spending more money here soon. Haha read more

All these guys had to do was grind down a small price to fit my guid rod. They had my gun for over one week and did nothing! Terrible service! Will not be coming back here for anything. read more

It's a little shop in a strip center in Lake Forest, but they were very helpful in switching out the sites on my Glock. Reasonably priced and quick. They seem to have a nice selection of firearms which I will check out next time I am in. Highly recommended. read more

FFL transfer was handled fine, but paperwork took a while and communication improved.

The people in here are great; Ron, Reza, Corey, and the lady have been a pleasure to work with on two separate occasions. I highly recommend them for their great work and fair pricing, I will be back! read more

Had an issue with my gun and needed it repaired after I caused some damage to my glock. Reza replied quickly via yelp. His price was very good. Great comms from this company. Went in and dropped it off and amazingly got a call the same day only hours later saying it was ready for pickup. Workmanship was excellent and friendly from all the staff. This will be my go to place for gunsmithing. read more

Reza and his team came through again with a custom Sig P320 build from a standard Sig M18. Couldn't be happier with the result! read more

The best gun smith around. He takes care of all my needs and requests. Always willing to help and advise. read more

Reza is awesome. Super personable and knowledgeable. In my experience, this world is not very welcoming, so his customer service went a long way. I highly recommend this place for any firearm purchases. read more

Was greeted immediately upon entering the store by Rez and Corey. True professionals, very kind and knowledgeable. Were patient with me while I was explaining what guns I had and what I was looking forward. Their customer service and knowledge is great. I would and will recommend them to friends and family (and strangers!) Thank you! read more

The guys have great knowledge and expertise in firearms and are always willing to help. They did a superior job installing my Apex trigger on my M&P Shield. Highly recommended gunsmith shop! read more

I needed help with some firearms to not be named in this review and my buddy who is a frequent partaker in the firearms world told me about OC Guns and this shop directly next door where he got a red dot site put on. I tried looking up the shop and nothing. So I went on faith and just showed up with a couple of firearms and met some of the friendliest gun people I've ever met! Right away Ryan helped me and gave me multiple options. He was so friendly and knowledgeable and the douche factor was a zero. And the Reza the owner came out with his lost surfboards hat on with a deep tan that showed he surfed as much as me. In fact there was surfing on the screen behind them on the TV both times I went in. Guns and surfing? Ok if there was tacos and beer i might have found Nirvana. But i digress. Go here. Reza and his team know guns and have been in the game a long time. The prices are fair and they do quick work. In fact they basically fixed all the screwups I made on my AR build for free along with some bigger work they were doing for me. I for sure thought they would add on some $$ for spending the time. But they chose gaining a customer for life and just did the job and went above and beyond. I highly recommend and i cannot wait to go back. read more

The Heavy Machine is a hidden gem in South Orange County for firearms and anything firearms related. The best part of this business is the care of the customer. The customer service here blew me away. Every time I've been into the shop I've been treated above and beyond by the owner, the kind of customer service that makes you want to come back and spend money in their store. For any firearm purchases, repairs or questions, Need an optic cut and installed, try these guys, great job, great price. The Heavy Machine is the place to go. read more

Great shop with knowledgeable and professional staff. Rez knows firearms and gunsmithing inside and out, and Corey is straightforward and reliable. I've bought, transferred, and consigned firearms here, and the process is always smooth. There are plenty of shops in OC, but this one stands out. Highly recommend it for excellent service and expertise. read more

Great store, ran by great individuals. Definitely will continue to come back. If you need a reputable FFL these are your guys.

It was my first time checking out this shop and I needed help with some of my clunky old guns to prepare for a camping trip. Reza (sp?) gladly showed me how to operate my guns, even oiled my handgun for me, and got it in nice working condition. I highly recommend this place and will be going here for any future firearm needs. read more

Rez modified my pistol by adding a Holosun open reflex sight. I am a new gun owner, and Rez was very helpful.

Quick service and fair pricing, they did great work on my M&P Shield and Glock 19. I've recommended this shop to all my buddies.

Excellent gunsmith, knowledgeable staff, great selection of parts and fair prices! What more can you ask of a business. I went in to do some upgrades on my stock Glock 19. Not only do they have a good selection of parts but they are happy to order it if not in stock. Reza the owner actually took my gun to the back of the shop and installed the parts while I waited! AMAZING.. If you know anything about gunsmiths, it is rare to see your gun ready before two to three weeks. I highly recommend The Heavy Machine! read more

Called in soon after they opened up to ask if they're able to replace the trigger for my P365 since I had anxiety and skepticism of trying to do that myself. The gentleman (who I think is the owner) picked up the phone and told me it could be done for $50 (reasonable price imo) and I drove right there soon after. Long story short, within an hour of dropping off my firearm, I received a text saying the job was done and it was all ready to go! Needless to say, I'm very satisfied with the customer service and quick turnaround. Definitely would recommend using their services for any gunsmithing or modifications! read more

Excellent work and communication. I had a 13.7 Upper that needed to get a muzzle device pinned and welded to be compliant. I walked over from OC Guns to check it out the new shop next door and met Reza. He said he could get the job done by end of day. I left it with him and within a few hours he texted me to let me know my upper was ready for pickup. When i got there, he explained to me what he did and how he did it. Not only was it completed, the pin and weld was very clean and sleek. I will be taking a 14.5 build for them to pin and weld soon. They also have Glock and other AR related products in the store. He also had boxes of 'batteries' from 9mm to 556 available for sale. 10/10 would recommend read more

I bought a used safe from this shop. These guys are SUUUUUPER fair. They even dollied it out to the truck loaded it. Obviously the customer service is out of this world so I'll be back read more

Reza is awesome. Has installed sights for me on a couple of pistols quickly and precisely. Highly recommend THC for any gun smith needs.

Had a PPT done at The Heavy Machine. Drove from LA twice and would probably go again just to do business with Reza again. Hospitable, patient, helpful. What more could you ask for. Even offered to stay open past their closing hours (ON A CINCO DE MAYO FRIDAY) to keep doors open for me. Ran my paperwork at lightspeed, then sent me on my way. Gave me a water on my way out after listening to me complain about traffic. Highly recommend giving this place a go. read more

great guys, very down to earth, reasonable prices, knowledgeable and do great work. Highly recommend for anything from upgrades/repairs, to buying/selling firearms. They really go out of their way to help you out. read more

Good guys. Knowledgeable. Great service. No issues finding a parking spot. Thank you.

Talk about professionalism and hospitality. Reza is an absolute expert and is so easy to work with. These guys treat you like family the minute you walk through the door. The Heavy Machine is a 2 hour drive from my house! But I'm not the only person who drives to Reza from that distance...why? Because he's the greatest. Much love guys! You deserve 10 stars! read more
