CZ527 10MOA Picatinny Rail

CZ527 10MOA Picatinny Rail

CZ527s love em’, I have two; a 222 Rem and 6.5 Grendel (both customs). This mini Mauser action offers a sweet and handy rifle. However, the ultra short receiver leaves little space between rings for length adjustment. Also, the dedicated 15mm bases precludes the fitting of longer rails if you need more eye relief or want to fit NV.

CZ, savage & remington

So, when I found out that Barton Gunworks (Professor Will Westlake) who produces a series of compact moderators was offering Picatinny rails, I was interested. They make for CZ’s 455 and 527 and Savage; rimfire and B-MAG, plus the short action Models 10, 12, and 16, also Remy 700 short and long actions. Never happy with the base/ring set-up on my Grendel, I took this opportunity to get a 10MOA rail.

Made in the UK, using high-grade aircraft aluminium, they are anodised with a high-quality satin black finish. They all offer a 10 MOA base (except the 455 model), allowing more scope elevation, but not so inclined that you can’t zero at 100 yards. All rails include screws and Allen keys. The design incorporates a true MILSTD- 1913 (Picatinny) build!

Wobbly vase

Will said this of his product: “Many current rail designs are not tight enough and result in scope movement, which can be highly frustrating when zeroing. It’s like putting an expensive vase on a wobbly table. This new design extends the length, allows easier mounting for perfect eye relief on longer scopes, as well as NV equipment and delivers better use of the elevation turret to shoot at longer distances, thanks to the inclined base.”

Fitting is simple and secure! The underside is cut with two compatible 15mm slots that locate precisely over the existing, dovetail receiver bridges. Two Allen screws per bridge ensure a 100% fit and the CZ side cut-out in the rear base is addressed by another, one more in front of the forward dovetail adds belt and braces security. My rifle had just been Cerakoted and I needed to tap it on with a plastic hammer, tolerances are excellent, as it shaved off a few thou of paint as it went on, to produce a rock-solid interface!

Now, the world’s my oyster for any optic, including NV, I choose to fit to my Grendel as to type and eye relief etc. This is an exceptionally fine bit of engineering that is surprisingly cheap, compared to some other offerings! Sadly, I cannot fit the rail to my 222, as the dovetail bases were machined slightly off bore line at the factory, so causing the scope to run out of right-hand windage adjustment. So I have to use an adjustable mount to compensate!

  • Hi.
    I have the same CZ 527 in 222Rem and the same problem: bases machined sligtly off bore line.
    Can you ship to Romania the set: rail and adjustable mount, for a Pulsar Trail XP50 thermal scope?
    Thank you!

    All the best,
