The Raven will be Canada’s most ergonomic, advanced rifle on the market. Precision machined, and packed with operator friendly features, you’ll be ready to crush the competition.

Lefty Friendly: We’re fully ambidextrous for safety selector, magazine release, bolt catch and charging operations.

Compatibility is everything: The Raven is already setup for top and/or side charging handle options making our platform fit your preferred style best.

Made For Canada! Our team at Lockhart pulled off the near impossible task of blending form, function, lightweightness while making a beautiful rifle specifically for the Canadian market.

Barrel Specifications: The heart of the Raven is it’s target smashing barrel. It’s match grade 18.6 inches of perfection is crafted from 416R stainless steel which is then 5R button rifled to squeeze every available milliradian of accuracy out of every round fired.  5R is an improvement over conventional rifling by changing the shape and configuration of the lands and grooves. Conventional rifling, while effective, can be improved upon in two ways.

  1. Conventional rifling has sharp 90-degree corners from the top of the land to the bottom of the groove.
  2. Conventional rifling has lands and grooves opposing one another. 5R rifling improves upon this by using 5 lands and grooves over the even numbers which puts lands opposite of grooves. Further, the transition from the top of the land to the groove is sloped.
  • 5R reduces projectile deformation as it passes through the bore during the firing sequence. By placing the lands opposite of the grooves, the bullets are no longer squeezed on opposite sides ensuring the projectile stays uniform instead of squeezing material into the grooves. More uniform projectile means better accuracy.

Bolt Carrier Specifications: Crafted from S7 Tool Steel and coated with a DLC (Diamond Like Carbon) coating. This coating is one of our favorites! It’s an extremely tough, corrosion proof coating that has a very low coefficient of friction and bonds so tightly to the carrier that it’s nearly indestructible. What does this mean for you? The Raven want’s to party without needing to be soaked in oil!

Our proprietary bolt system features a REAR half, and a FRONT half with a connecting cross pin. This allows you to only have to swap out the FRONT half during caliber changes while allowing instant and easy access to the firing pin and firing spring as well. We mentioned no tools required right?

Instead of requiring a proprietary extractor claw, we utilized a tested and proven off the shelf part to ensure replacements are always easy.

A Handguard like no-other: Our barrel is concealed by our proprietary aluminum hand guard. Understanding that one design doesn’t work for everyone, we have incorporated five (5) built in QD sling studs while only weighting a mere 0.77lbs!

Accessorize Yourself: We also offer a dual picatinny mounting solution. Use either the twenty eight (28) provided MLOK attachment slots, or use our thirty (30) threaded holes to attach additional rails on the 3, 6, or 9 o’clock position.

Tool-less Takedown: The Raven features beyond this world tool-less take down! Seperate the upper, lowers, handguard and bolt without any tools. Like the rest of the Raven. No other PCC comes close. Did we mention it takes under 30 seconds?

Featherlight: We optimized every feature of our weapon system while keeping the Raven incredibly strong; resulting a work of art. Weighing less than nearly every other “competitor”, the Raven is well balanced to ensure comfort while keeping you on target. Go dominate your sport with the Raven.

RAVEN – Full Tool-Less Take Down: YES
RAVEN – Bolt: S7 Tool Steel with DLC Coating
RAVEN – Firing Pin: S7 Tool Steel Heat Treaded to 55 HRC

S7 Tool Steel
S7 Tool Steel is a shock resisting tool steel with excellent toughness and high strength.
When compared to mil spec Carpenter 158, the S7 tool steel provides a 75% increase in tensile strength, and 60% improvement in yield strength.
When compared to 4140, the S7 tool steel is roughly an 102% increase in tensile strength, and 114% improvement in yield strength.

DLC (Diamond Like Carbon) Coating
This coating is one of our favorites! It’s an extremely tough, corrosion proof coating that has a very low coefficient of friction and bonds so tightly to the carrier that it’s nearly indestructible.

Cerakote Coatings
Cerakote is a ceramic polymer based proprietary formulation that offers industry-leading durability, hardness, scratch resistance, corrosion resistance, flexibility, heat, and chemical resistance. Since Cerakote has self lubricating elements incorporated through out the coatings matrix, firearms can function with little or no fluid lubricants minimizing typically abrasive dust particles which are attracted to oils.

RAVEN – Tool-Less Modular Caliber Change: YES
RAVEN – Ambidextrous Bolt Catch: YES
RAVEN – Ambidextrous Magazine Release: YES
RAVEN – AR15 Compatible Trigger Group: YES
RAVEN – DUAL Charging Options: YES

Why Ambidextrous?
While only about 10% of the population is left handed, many firearm owners train with both their strong side, and their weak side. Having symetrical buttons on both sides ensures you know exactly what you are doing on either side.

RAVEN – Upper Receiver Material: 7075-T6 Aluminum
RAVEN – Lower Receiver Material: 7075-T6 Aluminum

7075-T6 Aluminum vs 6061
Why does 7075 series cost more?
Tensile strength of 7075-T6 is nearly 200% Stronger than 6061-T6.
Shear strength of 7075-T6 is roughly 150% more than 6061-T6.
