Magpul has released a new modular chassis that should generate interest in tactical and PRS circles. Priced at $999.95, the Magpul Pro 700 Chassis is expensive — you can buy a complete Ruger Precision Rifle for less than that. But it looks like it has some impressive features that may justify the cost. The buttstock section features fast, ambidextrous controls for LOP and cheek-piece height. The Pro 700 features a strong, internal aluminum sub-chassis, with an universal bedding block section that works with both right-hand and left-hand actions.

Brownells Video Shows How to Cut Chamfer on Barrel Crown

brownells crown muzzle barrel bullet accuracy gunsmithing

This video from Brownells talks about a the crown of a barrel and how the crown’s condition affects accuracy. As the bullet leaves the barrel of the gun, the shape, alignment and the condition of the crown can affect the accuracy of your shot. A proper crown is essential to ensure that the bullet leaves the barrel correctly and that the propellant gasses behind the bullet are distributed evenly on firing. A square crown without burrs and a smooth transition will normally ensure consistency from shot to shot. By contrast, a damaged crown can cause unpredictable flyers that open your group. That’s why it’s important to have perfect crowns on all your barrels.

The video explains the different types of crowns that can be used. In addition, the video shows how you can chamfer your muzzle in a home shop. If you use a properly-sized pilot, cutting a shallow chamfer is something that most guys with some mechanical skill can handle. Just be sure to use lubricant, flush chips, and don’t rush the job. Cutting the barrel is another matter. At the 1:20 mark the video shows how to use a hack-saw to remove a damaged muzzle section. While this may be fine for an inexpensive rifle that needs a “quick fix”, we do NOT recommend using a hack-saw with a vise for a competition barrel. The reason is that it is too easy for a novice to produce a cut that is not square. We suggest letting a professional gunsmith cut and crown your competition barrels.
