MDT Buttstock LOP Spacer Weight – XRS, HNT26, Oryx, SCS-Lite & CCS
The MDT Buttstock Length of Pull Spacer Weight 105330-BLK provides a simple, effective way to improve rifle balance while adjusting stock fit. Each weighted spacer adds 0.8 lb (12.8 oz) of rearward mass and increases length of pull by 0.5 inches, allowing shooters to fine-tune rifle handling, weight distribution, and ergonomics.
Designed as a direct replacement for compatible MDT buttstock spacers, this upgrade is especially useful for precision rifle competitors looking to balance heavier barrels, optics, and accessories without adding unnecessary weight to the forend.
Improve Rifle Balance & Stability
Proper rifle balance can make a significant difference in how a rifle handles from supported shooting positions. A front-heavy rifle may require additional effort to stabilize, particularly during PRS and precision rimfire competition stages.
Adding weight at the buttstock moves the rifle's center of gravity rearward, helping offset heavy barrels, optics, and forward-mounted accessories.
- 0.8 lb Additional Weight: Adds approximately 12.8 ounces of rearward mass per spacer.
- 0.5" Length of Pull Adjustment: Increases stock length while adding weight.
- Improved Weight Distribution: Helps counterbalance front-heavy rifle configurations.
- Precision Rifle Competition: Useful for PRS, NRL22, and supported positional shooting.
- Modular Adjustment: Interchangeable with compatible MDT buttstock spacers.
- Simple Installation: Includes attachment hardware for compatible stock systems.
Compatible MDT Chassis & Buttstocks
MDT designed the 105330-BLK spacer weight for several popular chassis and buttstock systems, making it a versatile accessory for both new precision rifle builds and existing platforms.
- MDT XRS Chassis – 104689-FDE – An excellent application for shooters using the XRS in precision rifle competition. Rearward weight adjustment can help balance heavy barrels, optics, and forward-mounted accessories while retaining the XRS's traditional stock ergonomics.
- MDT HNT26 Folding ARCA Chassis – 107835-BCF – Although the HNT26 emphasizes ultralight construction, the spacer provides an optional way to add rearward weight when rifle balance and supported shooting performance take priority over minimum overall weight.
- MDT Oryx Sportsman Chassis – 104751-BLK – A practical upgrade for precision rimfire and centerfire Oryx builds. Additional buttstock weight can help balance longer barrels and front-mounted shooting accessories.
- MDT SCS-Lite (Skeleton Carbine Stock Lite) – Compatible with the SCS-Lite spacer system, allowing additional buttstock weight and length-of-pull adjustment.
- MDT CCS (Composite Carbine Stock) – Compatible with the CCS spacer system for additional weight and improved stock fit.
Compatibility Note: The weighted spacer replaces compatible MDT buttstock spacers. Verify your specific buttstock configuration and required attachment hardware before installation.
Fine-Tune Your Rifle for Competition
For PRS and NRL22 competitors, weight distribution is an important part of building a stable rifle. Adding weight at the rear can complement existing forend weights, helping shooters establish a preferred balance point for barricade shooting, prone positions, and supported stages.
The MDT LOP Spacer Weight provides a straightforward way to adjust rearward mass without changing the rifle's chassis or replacing its buttstock.
Because each spacer also increases length of pull by 0.5", shooters should consider both overall rifle balance and proper stock fit when selecting the number of spacers.
