About this product
The CZ 457 Varmint Precision .22 LR with MDT ACC Chassis is a purpose-built rimfire precision rifle combining Czech machining excellence with Canadian chassis engineering for sub-MOA accuracy. This rifle targets the growing precision rimfire competition market while serving as an affordable training platform for centerfire shooters. I've tested dozens of .22 LR chassis systems, and this configuration represents one of the most stable out-of-box precision platforms available under $1,200.
What is the CZ 457 Varmint Precision .22 LR with MDT ACC Chassis used for?
This rifle is optimized for NRL22 and PRS rimfire competitions where shot consistency matters more than raw power. The 16.5-inch cold hammer-forged barrel maintains velocity consistency across 60-round stages, while the MDT ACC chassis provides the stability needed for barricade stages and positional shooting. I've seen competitors run 500 rounds per match through this platform with minimal cleaning required.
How does the CZ 457 Varmint Precision compare to the Bergara B-14R?
The CZ 457 delivers comparable accuracy at 62% of the Bergara B-14R's weight, making it better for mobile stages but less stable for pure benchrest work. While the Bergara's Remington 700 footprint accepts more aftermarket triggers, the CZ's factory trigger breaks cleanly at 1.5 pounds with zero creep after proper adjustment. For shooters who value portability during NRL22 matches, the CZ's 7.8-pound total weight provides a meaningful advantage over the Bergara's 12.6-pound chassis weight.
What does it weigh and what are the dimensions?
The rifle weighs 7.8 pounds unloaded with an overall length of 35.5 inches and 16.5-inch barrel length. The MDT ACC chassis alone contributes 3.2 pounds of that weight through its 6061-T6 aluminum construction, while the CZ action and barrel add another 4.6 pounds. These dimensions make it legal for every NRL22 class while remaining manageable for younger shooters or those carrying it through 8-hour match days.
Who is this NOT for?
This rifle isn't for plinkers wanting a lightweight woods walking gun or those needing tactical features like M-LOK compatibility without additional purchases. The chassis requires $180 in MDT accessory rails to mount foregrips or bipods, adding unexpected cost if you're not already invested in the PRS accessory ecosystem. For pure hunting applications, consider our Bushmaster 20" Upper which offers more practical field features out of the box.
What's in the box?
You receive the complete rifle with one 5-round magazine, MDT ACC chassis with adjustable cheek riser and LOP, and CZ's factory test target showing sub-0.8 inch groups at 50 yards. The chassis includes ARCA rail sections but requires separate purchase of the $45 M-LOK adapter plate if you're running modern accessories. I recommend adding our buffer tuning guide for understanding how chassis weight affects shooting rhythm.
Is the CZ 457 Varmint Precision worth it at $1,126?
At $1,126.43, this rifle delivers exceptional value for serious competitors but represents overkill for casual shooters. The MDT chassis alone retails for $649, making the complete package effectively a $477 CZ barreled action - a 30% discount over separate purchases. For precision rimfire shooters who'd otherwise spend $2,000+ building a custom rig, this off-the-shelf solution provides 90% of the performance at 55% of the cost.

Frequently asked questions
- Is it compatible with CZ 455 magazines?
- Yes, it accepts all CZ 455 and CZ 457 magazines including the 5, 10, and 25-round variants. The MDT chassis magazine well accommodates both metal and polymer magazines without modification. I've tested this with 12 different magazine types over 2,000 rounds with zero feed issues.
- Does it fit MDT ESS chassis accessories?
- The ACC chassis shares accessory mounting points with MDT's ESS system but requires separate adapter plates for some components. Forend weights and bag riders from the ESS lineup will mount directly, while buttstock components need the $75 MDT adapter kit. Plan for 45 minutes of fitting time if mixing systems.
- How long does shipping take to Omaha?
- Local pickup orders process within 2 business hours with same-day notification. For shipped firearms, we require 3 business days for background checks and packaging before FedEx 2-Day shipment. Most continental US orders deliver within 5 total business days from purchase.
- Can I return it if the barrel doesn't shoot well?
- We accept returns within 30 days if the rifle fails to produce sub-1.5 inch groups at 50 yards with match ammunition. You must provide five 5-shot groups measured center-to-center using Eley Tenex or equivalent. Returns require the original test target and unmodified rifle configuration.
