YHM launches Graham Brothers Rifleworks with MARC Sport chassis for marksmen.
Within the firearms industry, the name Yankee Hill Machine is almost unavoidable when it comes to quality, affordable, American-made modern sporting rifles, components and accessories. For over 65 years YHM has proven itself as one of the leading developers of suppressor technology and modern sporting rifle accessories that will stand the test of time without breaking the bank. Now, having established themselves in that market, YHM is branching out with a new division, one that focuses on a premier product line and a particular customer.
Enter Graham Brothers Rifleworks, the premier product line for the precision marksman. This new brand will focus on top-of-the-line accessories and equipment designed for competition and long-distance shooting, primarily for bolt-action rifles. The MARC Sport chassis system is the brand’s initial release.

When developing this new superior chassis system, not only were accuracy and weight considered, but ergonomics, durability, adaptability and comfort were as well. Graham Brothers is currently in development of both supporting and stand-alone products for the precision shooting sports. With the experience learned through the success of YHM, Graham Brothers Rifleworks has established itself as a premier choice for the precision marksman.
Available for Remington and Savage platforms in both short and long actions, the MARC Sport can be optioned with either an A2 or carbine stock adapter. The chassis features “V” bedding for improved accuracy and will accommodate recoil lugs up to 3/8 inch thick. An integrated thumb rest allows for multiple grip positions for maximum comfort and precision.

All chassis accept AICS-style magazines and feature an ambidextrous magazine release lever. The chassis can also be complemented by two other accessories engineered to work specifically with the chassis.
The first and most notable is a handguard that extends the mounting surface of the chassis forward by 7.5 inches. It features M-Lok accessory mounting, Q.D. sling swivel points at front and rear locations, and is cleared to allow for large objective scopes.
The second accessory is an Arca-Swiss rail that accepts a wide array of adapters and accessories made to the RRS standard.
All the major chassis components are constructed of 6061-T6 aluminum and finished with a Type III Class 2 hardcoat anodize. Editor’s note: For more information, visit gbrifleworks.com.

James Yeager of Tactical Response demonstrates how different projectile weights affect overall sound suppression, and he uses a YHM Phantom. Maybe suppressor owners already know this or not, its worth looking at how the higher grains affect the sound. The higher the grain the quieter it got, simply due to the velocity not the weight. Very interesting video!

turbo-rifle-backSilencing the Competition with the new TURBO sound suppressor by YHM Yankee Hill Machine is proud to announce the release of the TURBO, the all new 5.56 suppressor. It was designed to meet the increasing demand for a quiet, yet lightweight sound suppressor that won’t break the bank. As the current state of the suppressor industry grows and evolves, the demand for a high-tech, cost effective suppressor becomes more apparent.

Since we first began milling out handguards as a firearms manufacturer, YHM has built a strong reputation on producing the highest quality products for the everyday shooter that doesn’t have access to an unlimited budget. The same YHM commitment lives on, bringing the modern suppressed shooter a superior product at an attainable price point.turbo-vert

The TURBO utilizes a tubeless design made from heat treated 17-4 stainless steel along with a heat treated 718 Inconel blast baffle. The combination of these materials allows the suppressor to be full auto rated and designed for rigorous use. The overall length measures 6.5” with a 1.5625” diameter -all while weighing in at a surprising 13.5 oz. Having an average sound pressure level of 134dB on a 14.5” AR shooting 55 grain ammo, the TURBO is well within the hearing safe threshold of 140 dB. Built with the same care, quality, and attention to detail that has defined the YHM brand for generations.

With an MSRP of $489 (which includes a Q.D. brake) the TURBO was created to supply the modern suppressor community with a full-featured suppressor at an affordable price.
