Andrew helped me out tonight with some parts, upper etc. great guys, super clean retail area and all the stuff you have on your wish list available or can be obtained quickly. I am more than impressed with this shop, lots of accessories, all the tactical “ish” gear etc. my new shop!”

“My husband and I had previously visited two gun shops and am sure glad we came to Firearms Unknown. Everyone in the shop has an awesome sense of humor. Adam demonstrated passion and great knowledge in helping us select the best gun to fit our needs. If you are looking for guns, supplies and entertainment Firearms Unknown is your one stop shop.”

“This is hands down the best firearms store in San Diego. The staff are beyond friendly, professional and beyond knowledgeable. If you have any firearms project and are going anywhere else you messed up!”
Kyle L.
National City Customer
“Very helpful in helping first time gun owners understand the process. We were among the many who bought our first weapon following concern about the lockdowns and riots. Many gun stores wouldn’t sell to first time owners at this time, or didn’t have the weapon in stock we were looking for. The man who helped us was ex military and was as helpful and polite as anyone could have wanted, and they had a great inventory to choose from.”

“Good shop. Good people. I have bought a lot of gear from this shop and they have great knowledge and customer service. They’ve helped me out when I’ve had questions. They have a large selection of gear with competitive pricing. I recommend stopping in!”

Oceanside Customer
“The most wonderful buying experience even getting through all the f’ing loopholes that Cali throws at ya. Thanks to all the staff for being professional, personable, friendly and funny as hell. As long as I live in north county I will be purchasing all my firearms here.”
Lindsay W.
Oceanside Customer
“Check this place out! I came here to purchase accessories for my AR. Grover was knowledgeable and helpful. I had a few questions about the best triggers and compliant fixed stocks. With California laws constantly changing, Hiram’s will have customer forever. This store has been newly remodeled and has a liquor store next store to help with multitasking. Guns and Liquor, they go together RIGHT!”
Cinna B.
El Cajon Customer
“This store may not have it all, not many do. If you are into upgrading your AR or building one from the 80% up, they have what you need. Not only that, these guys offer a great value as far as friendliness, knowledge and customer service. They don’t try to shamelessly up sell. They instead go out of their way to make you happy with your purchase. Currently my go to store. Worth a little extra drive for the quality and value I receive consistently at Firearms Unknown.”

“Cool store. Grate place to learn more about constantly changing laws in gun control here in California. Hopefully things change here in California… Until then we can count on Unknown Firearms to help us purchase the parts to build are own guns! Thanks guys!”
Nicholas Mielke
National City Customer
“This place is great! The staff Knowledgeable and invest there time in informing you while not being rude or condescending about it. I’ve been to many Gun stores especially the big chain ones like Dicks and Turner’s where it’s some kid or some old dude who just wants to “school” me or don’t even know what the weapon is chambered in. If you have a question these guys are always happy to spend time with you too get you in the direction you need to.”

“It’s a very good place to go had a wonderful experience I’ve been there several times. The guys are so friendly I even go from time to time just to talk or to ask questions or maybe for advice they never once made me feel like I was a burden or unwelcome I really appreciate it.”
Cory George
National City Customer
“Really great group of guys, very knowledgable of firearms, accessories and California Laws. I love how they can help smith your Firearms in shop to customize your personal needs and it shows the level of commitment they have to servicing their customers. Whether you are new to firearms, expert or somewhere in between you can guarantee you will walk out happy. They specialize in AR, they build their own uppers and test them out at another location. Each AR Upper is guaranteed for a lifetime! Highly recommend this shop!”
Justin Haler
El Cajon Customer
“I’ve been to 4 stores in the area, and Firearms Unknown is hands down the best. Due to the recent situation, very little supply is in stock at any store and lines are long everywhere. I bought an item and needed to exchange it, and Brent made it so easy, painless, and fast, that I thought I was at Costco for a second. I’m glad I bought most of my supplies here, the customer service is definitely worth the wait.”
Bruce Wayne
Oceanside Customer
“Grover was awesome! He answered all my questions about CA’s handgun roster and featureless rifles. I didn’t feel like I was being pressured to purchase anything even after asking so many questions. The friendly atmosphere really set the tone apart from all the other gun stores I’ve been to in the area. Would highly recommend this store for first time buyers and novices wanting to dive deeper into firearms. Definitely going back for my AR-15 build in the coming weeks. 5 Stars!”

“My favorite gun shop !!
I visited there last Sunday and received awesome customer service from Grover and Joel. The shop was really well stocked and the staff was very knowledgeable. I will be visiting them only from now on for all my firearm needs. A hidden gem….”

“Awesome staff and all of them are very helpful. Found this place randomly after in dire search of AR parts and luckily I was able to get my lower receiver here. Purchase was quick and easy. Grover and the other employees took care of me and I really like how they have a lot of parts that I can use for my future builds.”
Jay E.

“Staff was very helpful. Also, they had the night sights I needed in stock and cheaper then other places. They had a bunch of other parts for future builds too. Will definitely be back!”
Jacob M.

“Stopped in yesterday afternoon looking for a new low profile gas black and carbine length gas tube for my MSR free float upper build. Grover was working behind the counter and showed me the different options and colors they stock. I enjoyed talking with Grover and picking his brain. The staff here is very knowledgeable and well rounded on all the hot new products out on the market including answering questions on our ever changing and mostly confusing California gun laws. Great store and great customer service, A+”

“I love doing business here. Everyone I’ve worked with is polite, professional and knowledgeable. There is no holier-than-thou attitude if you aren’t tac’ed out in 511 gear and Oakley’s.
I came in to buy a trigger for my AR. I love that they have mockups to test the different triggers out and I ended up with a Geissele. I have never been disappointed with the service or products I’ve found here.”
Robert T.
National City Customer
“This place has amazing firearms and great people who work there who will answer every question you may have. As a first time handgun owner they spent all the time I needed. They also told me about Iron Sights shooting range. So, I’m excited to start training! Thanks guys!”
Mary-Kay T.
Oceanside Customer
“Great place to start or finish your build. Have many options to choose from and are knowledgeable about what they sell. They helped me get what I needed and make good choices for my build. Not my first time there and won’t be my last. These people were easy to talk to and weren’t the typical “gun store” salesmen. Prices are very competitive and I proudly support local versus online. Thanks again and I’ll be back.”
