Overview
Built for a Remington 700 chambered in .300 Win Mag, this chassis is intended to give the barreled action a rigid, durable platform for demanding use in varied weather and terrain. It includes adjustable length of pull with 10mm and 20mm spacers, plus a cheek piece that can be adjusted for both height and lateral position to help tailor fit. Six flush cup sling points and the KeySlot accessory mounting system add practical carry and setup options, while the included AICS 5-round magazine supports a ready-to-use configuration. The polymer and alloy construction, along with the optional folding stock setup, make it a versatile choice for hunters and shooters who want a more configurable chassis system.

Considerations & Trade-offs
- The chassis is built around a barreled action platform rather than a traditional stock, so it may not suit hunters looking for a simpler, lighter setup.
- Length of pull is adjustable with 10mm and 20mm spacers, which adds fit flexibility but also means setup may take some tuning to match your preference.
- AICS 5-round magazine is included, while 10-round magazines are optional, so higher-capacity use requires an additional purchase.
- The optional folding stock is not included as standard, so hunters wanting that configuration will need to add it separately.
