All information on the model MONOLITH 375 will be in this thread.
BespokeGun presents Monolith — a high-precision next-generation platform for calibers .33XC, .37XC, .375 CheyTac and .408 CheyTac.
In the BespokeGun lineup, the Monolith forms a separate long-range large-caliber segment. This is not a development of an existing system or its reinforcement for a more powerful cartridge, but an entirely new platform, originally designed for long and ultra-long distances, the heaviest bullets, maximum pressures, and high recoil impulse.
The creation of the Monolith took two years. The platform was designed based on BespokeGun's practical experience and conclusions drawn from the SMO. Real-world conditions of use, the nature of loads, contamination, maintenance limitations, and requirements for reliable operation were incorporated into the system already at the development stage.
The Monolith philosophy is built on the logic of a weapon for war. It was essential for BespokeGun to create a production platform combining military reliability, high safety margins, predictable operation, minimal required maintenance, precision manufacturing quality, and high accuracy. In terms of its level, the Monolith is created as a production system comparable to custom solutions from leading manufacturers.
The safety margin in the Monolith is part of the overall architecture of the platform. It was incorporated not as a reinforcement of individual parts, but as a fundamental principle of the system's construction. The design took into account not only standard operating modes, but also the extreme working range, including the behavior of components when parameters exceed normal limits and the priority of shooter safety in non-standard scenarios.
The key components of the Monolith were developed from scratch. The platform received an entirely new bolt group and a new stock, originally designed for long and ultra-long range shooting tasks and high load classes. Their design incorporated strength, rigidity, durability, service life, and the ability to maintain stable geometry across the entire operating range.
The Monolith high-precision shooting system was originally designed for calibers .33XC, .37XC, .375 CheyTac and .408 CheyTac and is intended for barrels ranging from 30 to 36 inches in length. This configuration allows the potential of heavy high-ballistic bullets to be fully realized and enables operation at the ranges for which the platform was created.
The Monolith rifles feature an extended carbon magazine with a length of 128 mm, designed for long-range ammunition. This solution is part of the overall platform architecture and meets the requirements for strength, durability, low weight, and operational stability.
Special attention during the creation of the Monolith was paid to balance and the overall operation of the system. For a platform of this class, not only strength is important, but also proper mass distribution, stability on a support, predictable behavior under recoil impulse, and shot-to-shot repeatability.
Accuracy for Monolith rifles is considered a systemic property. It is expressed not only in grouping, but also in geometry retention, operational repeatability, characteristic stability, and result reproducibility throughout the entire service life of the platform.
The Monolith was created as a unified system in which all key elements are subordinated to a single task: to ensure reliable, predictable, and accurate operation where other solutions have already reached their limits.
The Monolith is a BespokeGun high-precision platform of a new class: for war, for large caliber, and for tasks where conventional solutions are insufficient.

New BespokeGun production trigger
Specifications:
• trigger pull weight: 227–907 g
• precise pull weight adjustment
• pre-travel adjustment
• no play
• predictable break
• dry trigger character
• stable operation
The break is dry and clean, with no overtravel or excess movement.
Measured Peterson Match 375 cases. Nothing special — wall thickness variation up to 0.0015! Peterson cases in calibers 33XC and 375 are far from ideal — that's already a fact.
Also measured the bullets. Imported turned bullets and A-type 390. The diameters differ and how they will fit the barrel is a very interesting question.
