Using a Qualified Individual to Install Pre-Fits

When considering a variable shoulder prefit barrel, (ones that use a torque nut opposed to integral shoulder), make sure a qualified individual who has the proper tools and gauges can perform a functional install for you, as well as hold all liability related to proper headspace

Picking the correct pre fit gun barrel

FAQ - PreFit Gun Barrels

Here are our instructions for ordering, and installing pre-fit gun barrels

We are frequently asked the question of whether or not installing a barrel nut is as repeatable as a shouldered barrel. The answer is a straightforward yes. We manufacture our barrel nuts in house and have no runout between the internal threads and the torquing surface, which ensures the same barrel/receiver alignment as a shouldered barrel. However, there are a couple of differences we should note:

Installation of barrel nuts requires more effort/skill. Variable shoulder prefits require proper headspacing gauges, as well as a qualified gunsmith to install correctly. Improper installation can cause harm to the shooter, others around, the firearm itself, and surrounding objects.
Barrel nut prefits are cosmetically different on certain receivers. Utilizing the thread size to dictate the barrel shank diameter, these types of barrels are smaller in the breech area, typically 1.062” versus 1.200”+. We designed each barrel nut to be as ergonomic as possible to achieve maximum functionality and user-friendly look and feel. Chassis builds allow seamless use, while major stock makers are creating inlets for nuts, some stocks require fitment.

There are two Savage shank sizes: standard and magnum. The standard nuts are .875” (7⁄8”) long and the magnum is .625” (5⁄8”) in length. Due to the fact that models feature both shank sizes, it’s not as easy as saying that a specific model has one and only shank size. Measuring the headspacing nut is the fastest and easiest way to tell the two apart from each other.

Updated info! Measuring the barrel nut is no longer a sure fire method of determining your shank size! You will want to measure the diameter of the barrel shank itself. The small shank ≈ 1.06" dia and the large/magnum shank ≈ 1.12" dia.
