US Optics Announces Fresh Run Of MST-100 Clone Scopes
If you are working on an M40A1 clone, this one is for you! US Optics is releasing a new run of MST-100 scopes. This fixed 10x optic was used on several US-issued sniper rifles and is often the missing piece in clone builds.

Unlike most scopes in production today, which use aluminum bodies, the MST-100 is steel. The original design dates back to the Unertl 10x Scope in the 1970s. Those eventually started wearing out from decades of use, and US Optics began refurbishing and upgrading them to MST-100 specifications in the early 2000s.
This run of MST-100 scopes is limited to 100 pieces. The pre-orders are not open until April 1st (no, this is probably not a cruel April Fool’s joke), but if you want a reminder when pre-orders open you can sign up here. If you want one be ready to drop some serious money: the pre-order deposit is $1,500, and the full retail price is $3,500. While that is a lot of money, it’s a good deal compared to an original Unertl 10x at around $5,000.
From the manufacturer:
“Originally developed in the 1970s by John Unertl for the USMC, the MST-100 was purpose-built for the M40A1 .308 rifle and later adapted for the .50BMG. Designed for uncompromising durability, its housing and turrets are precision-machined from 1018 steel, ensuring reliability in the harshest conditions. The elevation turret features an integral BDC calibrated for M118LR ammunition, with a veneer ring for fine-tuned ½ MOA adjustments.
In 2000, U.S. Optics took on the refurbishment contract, rebuilding these legendary optics to an even higher standard. To accommodate the M40A3’s 30 MOA base, we replaced the original leaf springs with a tapered coil spring, delivering flawless tracking. The scopes were further enhanced with a rugged Teflon coating for superior corrosion resistance. The original wire MIL-Dot reticle was upgraded to a recoil-resistant design, engineered to withstand the punishing forces of the .50 caliber platform.
Due to overwhelming demand, U.S. Optics is releasing an exclusive production run of just 100 MST-100 scopes. With modern materials and CNC precision, this limited-edition optic delivers legendary performance with contemporary advancements, standing among the finest precision scopes available today.”
