The Culper Precision Patrol rifle is our entry level MILSPEC rifle. All components are individually Gauged and verified against Technical Data package at the time of assembly. Its a perfectly executed base model AR-15.

DM - Designated Marksman

The Culper Precision ‘Designated Marksman’ (DM) rifle is the first of our ‘MILSPEC+’ or as we say ‘Culper Spec’ rifles. the Designated marksman is a Recce style rifle, in 11.5″, 14.5″ P&W, or 16″ with Ambi controls, Ambi charging handle, our individually gauged and inspected DLC coated bolt. This rifle is built with STRICT , INDIVIDUAL adherence to tolerances that either equal or far surpass MILSPEC tolerances for part relationships delivering a rifle that performs from a reliability and accuracy standpoint as good or better than many rifles double it’s cost.

DMSR – Designated Marksman Suppressed Rifle

The Culper Precision Designated Marksman Suppressed Rifle (DMSR) is specifically engineered, and intended for use as a dedicated suppressor host. We started with our Designated Marksman rifle and MILSPEC+ (CulperSpec) build formula as a base and enhanced it with suppressor-friendly components and tuning that simply no other Ar-15 manufacturer is doing currently. The result is a rifle that exceeds expectations for suppressed AR-15s, delivering the smoothest ‘recoil quality’ on the market, quickly returning to natural point of aim without the need for coercion by the shooter during strings of multiple follow-up shots. The DMSR has been lauded for it’s ability to reduce gas blowback on the shooter’s mouth and nose, allowing for operators to deliver multiple shots on target while staying focused on the target, rather than the discomfort commonly found while shooting suppressed.

Sierra Precision Rifle - SPR

The Culper Precision Sierra is a modern take on the Special Purpose Rifle (SPR) and the subsequent Mk12 variations that came from the development of the special purpose receiver and rifle programs. It is a high-precision, AR-15 pattern rifle designed specifically for our customers competing in the Tactical Games Sniper Challenge. It excels at long-rage, small-game, predator hunting, or counter-sniper operations. The Sierra is a highly precise, easy to operate, versatile, tune-able, and effective sharpshooting platform for modern shooters pushing the limits of the heavy, high BC .223 caliber projectiles. The Sierra is a perfect platform for learning long range shooting, utilizing more affordable ammunition, from an affordable, high-end precision rifle.

LSS - Light Sniper System

The Culper Precision Lightweight Sniper System (LSS) is a high-precision, small-frame, AR pattern Precision rifle. Designed initially for Law Enforcement sharp-shooters working overwatch, in the right case, it can resemble a media kit more than a SWAT operator’s rifle allowing for less time wasted by the SWAT operator having to access the overwatch hide hours before an event to set up incognito. The LSS is very popular with serious predator or hog hunters to reach out and touch that call-shy ‘yote or the stubborn sow hanging back in the dark woods. This system is available in 6 ARC, or 6.5 Grendel giving the optimum balance of ballistic performance and liability mitigation through auto glass, commercial glass, and barriers, or heavier hitting terminal ballistics than 5.56/.223.

Culper Precision Warrior Legacy 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.

Sourcing

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.
Machining

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.
Cerakote application

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.
Quality control

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.
Assembly

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.
Warranty

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%.
