This 0.35oz, 4 slot Picatinny rail is designed with specific features to make for an extremely secure mount to any style of stock with weight saving and durability in mind.

Flat rails contact a rounded stock at a single point, and have a tendency to roll and move with applied pressure. Our Unique 150° included angle means you will have two points of contact against any stock, making for a secure connection regardless of your stock's geometry.

Sling studs don't facilitate the mounting of other accessories such as bipods, but you might not want to ditch your sling entirely. Our unique Ultralight rail gives you the flexibility to run a bipod or other accessory while still maintaining the ability to attach a sling to the rail.

The 150° included angle also features 0.050" flats outside of the angle to give a solid fit to stocks/chassis which are completely flat. In addition, we've also used a Pin and Slot design for the fasteners, which provides flexibility to work around unique features of your stock when choosing a mounting location.

Machined right here in the USA out of billet aluminum and including stainless steel hardware. The premium materials and black anodized finish provide excellent resistance to wear and the environments.

Great customer service

I ordered a ultralight Picatinny rail and let Wiser Customer Service know when it hadn’t been delivered in 45 days. They sent a replacement by courier and it was delivered to Canada in three days. I couldn’t be happier with the way they treated me. This is solid company that you can trust. And the Picatinny rail is great 👍

Great quality

Comes with everything you need and is extremely nice quality.

Perfect Fit, CZ 457 American .22lr/.17hmr, walnut stock, 24” barrels

I bought this 4 slot picatinny rail to attach a Hatch Outwest bipod to my walnut stocked CZ 457 American. The installation went easily measuring off the existing sling stud mounting hole, I marked and drilled the holes then counter sunk the included T-nuts with a 3/4” fostner bit on the inside of the stock. When the rail was attached it was a solid fit without any gaps and it fit perfectly between the end of the stock and the forearm checkering. This is a nicely made product from Wiser Precision and I wouldn’t hesitate recommending it.


This is the second type of rail I bought. The first one was cheap and sucked. I bought this one from wiser precision and it is perfect. It is contoured to fit a rounded stock. This is the only one you need. Buy it, you will be more than happy. Now I need one for each rifle!!!!!!

Super high quality

I bought a simple picatinni rail. Ultra lightweight, high quality. More importantly, this company makes a better tripod head than the more popular Outdoorsman head. When I switch to Arca, the WIser head will be what I buy.

Exactly what I was looking for!

Wiser Precision produces awesome and quality solutions. Perfect to attach my Gunwerks Elevate bipod to my rifle. Keep it up!

Needed for the quik clip

I bought this so I could mount the quik clip to my rifle. I have a Savage with a composite stock and I was able to use the existing sling bolt hole and I just needed to mark and drill the other hole. was really easy. Feels really solid. Happy with the design and build quality. I just wish Wiser would make it more obvious that you may need this piece for the quik clip. I had to make 2 orders

This mount is an excellent value with plus features including sling swivel mount and an excellent mounting hardware election with stainless steel fasteners and Tee-Nuts (wood application design.)
