The Culper Precision AR-15
The Culper Precision Patrol rifle is our most affordable rifle. This rifle is trusted by responsibly-prepared citizens and many agencies and departments around the country. This is a great option if you are looking for an accurate and dependable rifle that “keeps it simple” while providing a performance level that leaves every other rifle in this category in it’s dust.
The Culper Precision Designated Marksman (DM) rifle is a perfect balance of feature-set and performance in a value that cannot be beat. The DM is purpose-built for accuracy, reliability, ease of maintenance, and durability. The DM is the answer for the shooter looking for an optimized tool for self-defense, training, duty-use, or a “work” rifle. The DM is our most popular, and most versatile rifle platform.
The Culper Precision Designated Marksman Lightweight (DML) rifle has the same feature-set as the standard DM but with a tapered- pencil (.625″) profile barrel. This model reduces the weight of the rifle making for an easier to carry option. Our most popular “everyday AR-15” model.
The Culper Precision Designated Marksman Suppressed Rifle (DMSR) is specifically engineered for use with a suppressor. It used our Designated Marksman rifle as a base and adds several suppressor-friendly features including a specially tuned gas system, gas-busting charging handle, concentrically-mounted suppressor adaptor, and an A5 buffer and receiver extension. The result is a rifle that exceeds expectations for suppressed AR-15s by running more efficiently, smoother, and cleaner than other suppressed ARs. The DMSR also runs a Geissele two-stage match trigger as standard.
The Culper Precision Lightweight Sniper System (LSS) is a high-precision, small-frame AR pattern rifle designed specifically for Law Enforcement sharp-shooters. This system is available in three calibers (6ARC, 6.5 Grendel, and 6.8 SPC II) giving the optimum balance of ballistic performance and liability mitigation. The LSS platform includes a Magpul UBR Gen2 stock, Law Tactical folding stock adapter, Larue two-stage match trigger, Integrated ARCA rail on the handguard, and ambidextrous gas-busting charging handle.
The Culper Precision Lightweight Sniper System-Hunting (LSSH) is the AR-15 hunter’s dream rifle. A high-caliber lightweight build with very little recoil. It carries many of the same features as our LSS model, but ditching the folding stock adapter for a lightweight carbon handguard and Proof Research carbon-wrapped barrel. The LSSH makes an excellent deer-sized game hunting rifle that can be packed into the field in a much more compact and lightweight configuration than traditional hunting rifles.
Culper Precision Warrior Legacy rifles are one-of-a-kind custom rifle builds that replicate specific rifles carried by American Warfighters. These builds are executed to the exact same standards we have for all of our rifles, but are exacting replicas of specific firearms carried by America’s heroes. Currently our Warrior Legacy Rifles are exclusively available through Warrior Rising events and fundraisers.
How we build our rifles
Culper Precision AR-15 building Tenants:
Reliability/Durability: Our rifles are engineered and manufactured with the highest standard of reliability as the foundational core. The weapon system MUST be reliable! All other factors are secondary. Over-gassing an AR will contribute to immediate reliability, but it will also reduce the durability of the platform all other factors being equal. We balance our gas systems to ENSURE reliability, but to promote long-lasting components and durability of the system.
Accuracy/Consistency: We build our rifles to hold the highest standards of accuracy currently available in the AR platform. Even our base models are held to the standard of 1 MOA with 75grain Speer Gold Dot ammunition. We also build our rifles to remain accurate when the heat up, and to continue to produce small group sizes under demanding firing schedules. We use components that HOLD their tolerances over the longest lifespans and most demanding conditions. We use manufacturing practices that the “big guys” cannot because of their massive volumes. We take the time to build the rifle the right way from the very beginning. This gives you the most consistent, and accurate rifle available.
Ease of Operation/Shoot-ability: We engineer our rifles to be easy to use. What this means to us is that our rifles have great triggers and smooth recoil impulses. The have feature sets that promote fast reloads and malfunction clearances and that allow the user to operate the platform without undue distraction so they can remain engaged in dealing with a potentially life-threatening situation, or training for the same. The balance and ergonomics of our rifles help operators in finding NPA easily, and our gas systems help the rifle return back to NPA quickly allowing the operator to deliver fast AND accurate fire. We pay close attention to the dynamic performance of our rifles and to things such as recoil “quality” because they help the operator get the most of their rifle.
Value: Many manufacturers do a good job with meeting one or more of the preceding tenants but you will find the closer they get to meeting the standards that Culper Precision holds in these categories the more expensive their rifles become. At Culper Precision we believe that high quality defensive tools should be available to as many law-abiding and freedom-loving individuals as possible. We build this value into our rifles – striving to keep cost to the customer down as much as possible without compromising our standards.
The balance of dependability, accuracy, precision, and value is optimized for the customer starting at the very beginning of our rifle building process. We select every part of our rifles with the intent of producing the best quality product at reasonable cost. In-house creation of every part of the rifle is not an effective balance of performance and value for a small manufacturer, and it passes the cost on to the customer. Today there are several top-tier component producers for parts such as barrels, bolt-carrier-groups, stocks and so forth. We source these parts direct from the same companies who build for the “big brands” that most AR-15 shooters know. Many of our partners also manufacture these components specifically for us – such as our barrels and handguards. The end result of our sourcing process is that the customer gets the BEST COMPONENTS ON THE MARKET AT THE LOWEST POSSIBLE COST.
We feel it is extremely important to be able to maintain a high level of precision during several critical phases of the rifle building process. During these phases, we utilize our IN HOUSE machining capabilities to build our rifle parts. Specifically, our receivers are machined in-house using forgings sourced from Cerro Forge, Anchor-Harvey and Cardinal Forge. Machining these parts in house from the best raw-materials we can source ensures that we consistently meet our demanding parameters. We also keep very strict standards of quality control as we accept machined parts from partner manufacturers and component providers. Substandard parts are rejected.
Gauging and inspection
Using an extensive inspection process we individually gauge, measure, and test fit every critical piece of the rifle. This leads to improved gas efficiency, reduced parts wear, extended reliability, and higher accuracy. Specific attention is paid to the barrel, bolt, carrier, gas block, gas tube and upper and lower receivers. our inspection, machining, and assembly procedure includes more than 300 specific inspection points for each rifle. Our inspection is among the most rigorous in the industry. It follow techniques developed through decades of building, inspecting, maintaining, and using AR-15 platform rifles. These things are not all super-secret, but they are time consuming, and in some cases labor intensive, so very few manufacturers make the effort to follow such a demanding inspection and assembly process. Parts that do not meet or exceed our rigorous standards are corrected or rejected.
All of our rifles come with an expertly-applied, single color Cerakote finish as standard. Additional camouflage patterns, battle-wear patterns, multi-color designs and full-custom themes are available at customer request. Cerakote is a ceramic based coating that increases abrasion, weather, and corrosion resistance allowing our rifle to excel in the most extreme environments. Cerakote is the most widely-used modern firearm finish in the world and our Cerakote applicators are factory trained and Cerakote Certified Advanced Applicators. We apply all types of Cerakote including “C-Series,” “H-Series,” and “V-Series.” Near-Infrared (NiR) signature-reduction finishes designed to conform to the NIR reflectivity standards outlined in MIL-DTL-44436, are available, but with limitations due to Cerakote.
After Cerakote is applied we go over the fit and finish of the rifle to ensure the parts were coated correctly. If something doesn’t pass our strict quality control standards we will fix it or throw it out. Before assembly of the rifle, all of the parts are inspected (some of them are inspected multiple times) to ensure they meet our rigorous quality control standards. A checklist for this inspection and assembly that is followed for every rifle we build to ensure that standards stay high and nothing is missed, even if it is built at five o’clock on a Friday.
Each rifle is hand-assembled by one of our gunsmiths using an extensive procedure checklist that includes multiple proprietary processes that maximize accuracy, consistency and reliability. Some of the assembly processes are part of our own “secret sauce,” but many of them are well known “tricks of the trade” that most of the larger manufacturers just cannot take the time to do for EVERY rifle. Our status as a small manufacturer really helps during the assembly stage and allows us to build rifles that are truly top-tier performers because we can give each rifle the attention it requires rather than doing “spot-checks” or “batch-testing.”
Test-fire and final inspections
Once the rifle has passed quality control and has been assembled, we test fire them. – every single one of them. This gives us another opportunity to ensure everything is preforming exactly as it should. When the rifle passes test-firing is is given a final quality control inspection and the customer is contacted to coordinate delivery or pick-up of their new Culper Precision Rifle.
No rifle runs forever. At Culper Precision we do everything we can to ensure that your new rifle runs flawlessly for as long as possible. All of our AR-15 rifles carry a lifetime warranty against manufacturer defects. Our AR-15 barrels are very accurate and long-lasting – and we stand behind them with both accuracy guarantees and longevity guarantees. All of our rifles are guaranteed to shoot sub-moa groups with high quality ammunition, and to continue to do so for the practical lifetime of the barrel. We specifically use 77gr. Speer God-Dot Duty Ammunition to test our rifles (not match ammo) because our rifles are specifically designed for defensive and duty use. If you manage to “shoot-out” one of our barrels – contact us. We will inspect it, and if necessary, we will replace it. If you manage to otherwise damage one of our rifles in normal use (you didn’t do damage to it purposely) contact us and we will make it right again. We want you to have utmost faith in your new rifle and to have confidence that it will run properly, and continue to serve you for many, many years. We stand behind our product 100%.
