Would like the option of 2.5" 3" also. Using it for Chrono attachment and tripod. Also simplifys sling attatchment with no extra hardware.

I needed to add a bipod to my Mesa Long Range in 7mm. It’s a HEAVY rifle. As for some of us, I’m sure, it was hard for me to swallow the price of this little rail. Yes I shopped around and did the Amazon thing but those just didn’t fit right. Honestly I should have just bought this right off the bat. The fit is amazing! It’s nice and tight with absolutely no wobble at all! Absolutely worth the extra cost!!!

The rail is perfect for my needs. Well made. The screws that come with it are way too short though. They should be longer, even if we had to cut some off later. I had to order longer ones on e-bay. Also one of the the threaded female inserts should have had one more to match it. It comes with two of one kind that I did not use, and one of the kind I needed instead of supplying two. Why did they do that?

The following chart reveals CERATIZIT Sacramento (formerly PROMAX Tools) recommendation regarding how many feet your end mill should travel, per minute, in the material that you are cutting.

Should you have difficulties determining the proper SMF for your job, please contact the very knowledgeable CERATIZIT Sacramento Technical Department at 800-878-0502. We will be happy to assist you with your calculations.

Picatinny rail designed to attach to the forward sling stud location on rifles. Compatible with the MIL-STD-1913 spec. Measures 4″ in overall length and features an integrated sling mount location.

Surface Feet per Minute (SFM) is the unit of velocity used in machining to identify the machinability ratings of a specific material.

Once the SMF is determined, this information can be used to help decipher the proper starting point for the feeds and speeds needed while using  PROMAX Premium and DESIGN-RITE XL end mills on your particular job. Whether you are using our roughing end mills or finishing end mills, the following information is critical in determining where you should begin. Please note that the results are a starting point and may need to be adjusted in order to gain optimum results.
