Otter Creek was a new entrant to the suppressor business, having produced several bolt gun suppressors and, in 2021, entered the clone rifle world with a reproduction of the Ops, Inc #12 suppressor, which is known for being used on the Mk12 SPR sniper rifle. Otter Creek Labs has seized the opportunity sell an AEM5 style suppressor, which in 2021 was at a time when the true to form Allen suppressor were not available.
Otter Creek's Ops Inc. clone uses a Titanium tube to lower the over weight and 17-4 stainless baffles. The Otter Creek OCM5 looks and works very much like the Ops, Inc. #12 and the Allen Engineering AEM5. While Otter Creek is building its own different barrel adapters, the OCM5 will fit snugly on a Mk12, RECCE or Gordon barrel with an actual Allen Engineering collar and mount.
Like the AEM5 and the Ops Inc #12, the OCM5 fits over the barrel and needs a tapered collar to abut to, and threads to the external threads of an Otter Creek or Allen Engineering muzzle device. The OCM5 served a need during a period when real Allen cans were in very short supply. Some have reporting liking is lighter weight, and the lower cost, most military clone rifle enthusiasts report that they prefer the true Mk12 clone that Allen makes. Clearly, it is a personal preference.
All Mk12 suppressors, used on the Mk12 and the Gordon Carbine or NSW RECCE need a very precise fit, and the barrels require a special taper. Charlie's recommends that you get the right barrel, which we can help you with. The OCM5 was originally made by Otter Creek Labs in the 2021 and 2022, when Allen Engineering AEM5 suppressors were not widely available. Since 2022, Charlie's generally has the Allen AEM5 in-stock, but will occasionally buy the Otter Creek replica, when available by other dealers who are having difficulty selling the OCL suppressor.
The OCM5 filled a need in 2021 and into early 2022 when the Allen Engineering AEM5 suppressors were hard to find.

Otter Creek Labs Suppressor – Economical Performance for Budget-Conscious Shooters
Not every shooter needs a top-tier, premium-priced suppressor. Many simply desire effective sound suppression at an affordable price. The Otter Creek Labs (OCL) suppressor delivers exactly this—solid value without breaking your budget.
However, sourcing affordable suppressors can often lead to compromises in customer experience, reliability, or business integrity.
This can be frustrating, especially when dealing with suppliers who struggle with consistent delivery timelines and professional interactions, causing unnecessary headaches for retailers and customers alike.
Affordable Pricing: Provides solid sound suppression performance at an accessible price point.
Reliable Construction: Adequate materials and workmanship for recreational and entry-level suppressor users.
Ease of Maintenance: Simple design makes it straightforward for casual shooters to maintain.
Effective Sound Reduction: Meets the needs of recreational shooters without premium costs.
Charlie's Custom Clones no longer maintains an active business relationship with Otter Creek Labs due to consistent operational disappointments, missed deadlines, and subpar professional interactions. Otter Creek Labs has requested the removal of our listings, and although we earn minimal profit from these suppressors, our obligation remains clear: If we legally purchase a product, we legally offer it to our customers.
When excess OCL stock becomes available to us, we choose transparency and customer choice over convenience. Despite our challenges with the business relationship and the unprofessional behavior we’ve experienced from OCL's management, their suppressors remain a fair choice for budget-conscious buyers. Importantly, we have received no negative feedback regarding Otter Creek Labs' warranty service, which remains directly between OCL and the end-user.
While our direct experience prevents us from wholeheartedly endorsing their business practices, the OCL suppressor itself represents reasonable quality and affordability.

That’s it! We try to make this process as simple as possible for our customers. Please click the “Buying a Firearm” tab at the top of this page for more information.
THIS IS A SERIALIZED ITEM. It must ship to a Federal Firearms License holder. No civilian exceptions.
Buying and shipping through Charlie’s is easy, but there is some information you need to know. Only a federally licensed firearms dealer may receive a firearm or federally regulated serialized item (like a receiver or suppressor). We cannot ship these items directly to you. Please follow these steps to process your transaction:
1) Check your state laws to make sure the federally regulated item you want to purchase is legal in your state. Your FFL dealer should be able to give you all of the necessary information regarding your state specific laws. But, if we ship to your FFL, and there is a legal issue, we cannot accept a return. So please make sure that you know and follow your local and state laws.
2) A quick google search will show you what Federal Firearms Licensed (FFL) dealers are in your area. When you are ready to purchase, contact the FFL dealer you would like to use and get their shipping address. During the check-out, put YOUR address in the “billing” section and the FFL DEALER’S address in the “shipping” section. If you don’t know your FFLs address, that’s okay. You can send the information later.
3) After check out, make sure to contact your FFL dealer to ensure they will receive your shipment for you (most do this for a small fee, but you should always double check).
4) Have your dealer send us a copy of their FFL to FFL@CharliesCustomClones.com. Charlie’s does not reach to your FFL (MAKE THEM EARN THEIR FEE!!!)
5) Be patient! In order to ensure we remain compliant with all federal laws, our compliance department is kept separate from our sales and operations team. Please allow a few days for our compliance officer to verify all of your dealer’s documents and ensure all federal laws are being observed. You should hear from our compliance department within 3-4 business days. If not, feel free to reach out for a status update.
That’s it! We try to make this process as simple as possible for our customers, but if you are unfamiliar the process or have any other questions, please visit our How to Buy a Suppressor page for more details.
