Rechambering a Model 700 Remington action from .222 Remington to .224 Valkyrie entails going to a shorter and larger diameter cartridge. We’ll accomplish this by enlarging the chamber and utilizing the existing barrel threads while not giving up much barrel length in the process.

MasterPiece Arms was named the of the Official Chassis of the 2019 Precision Rifle Series season, marking the third consecutive year the company earned the distinction. MPA Chassis are machined from 6061 aluminum, have a V-bedding system, adjustable cheek piece and length of pull, a recoil pad adjustable for height and cant, Picatinny rails for optics and accessories, multiple QD sling swivel attachments, and built-in bubble level. MPA Chassis can be had for an ever-increasing list of barreled action, including Remington 700 Short and Long, Savage and Howa Short or Long Actions, Badger M2013, Mauser/Springfield, Surgeon, Stillers, and others. All are available in a variety of Cerakote finish and color options.
To give back to the shooters, MPA sponsors multiple PRS matches throughout the year, including the 2019 PRS Finale scheduled November 15-17, 2019. The Precision Rifle Series is a series of nearly 40 competitions throughout the United States with the largest being the GAP Grind having hosted over 400 competitors at the 2018 event. The Series tracks over 5,000 competitors competing in numerous Regional Series events consisting of local, one-day matches. PRS competition can be described as a blend of conventional and practical/action shooting. Rather than firing at static targets with concentric score rings from rulebook-prescribed positions, PRS shooting is done on steel targets of varying sizes and distances from varying positions and places of support, or lack thereof. The precision elements common to conventional competition are there as the targets usually subtend only a few minutes of angle and must be hit based on current environmental conditions. The action elements include ever-changing shoot scenarios and positions with elapsed times commonly used to break ties among competitors with an equal number of hits. Skilled shooters have described it as an ideal way to practice field marksmanship for designated marksmen and snipers.
“At MPA, we’ve made a commitment to the long-range shooting community and we are truly honored to once again be named the Official Sponsor of the PRS season. When you purchase one of our chassis, we never want you to regret that decision, and that is why all our chassis are backward compatible,” said Phil Cashin, owner of MPA. “We are out on the range, in the field, and at the matches with our customers, listening to their feedback and continue using it to produce a better product for them. We are committed to producing an innovative, quality-built chassis that every shooter can rely on.”
MSRP for the MPA Chassis ranges from $999-$1,150 depending on options. MasterPiece Arms uses high accuracy CNC machining, turning, laser cutting, and bending in its manufacturing process controlled by their ISO9002/TS16949 Registered Quality System.

Tormach Inc. is now offering servo motors for its line of 1100M and 770M CNC milling machines. Servo upgrade kits are now available for current users of these machines, which allows them to transform their current ‘M’ series machines to ‘M+’.
Complete information on obtaining the user-installed servo motor upgrade kits, with video tutorials, can be found on Tormach’s website: https://www.tormach.com/m-plus-servo-upgrade-kit/
Users who upgrade to servo motors will enjoy numerous benefits, including:
-Faster speeds – more than double feed rates
-Higher acceleration – allows machine to get up to speed much quicker
-Reduced noise
-Closing of the feedback loop into the control system
-Time and money savings on every part made
Tormach has released a video that is available on YouTube that shows examples of the time savings that can be achieved using the servo motors over the conventional stepper motors:
“For the vast majority of machinists using our 1100M and 770M mills, upgrading to the servo motors is an easy decision,” said Lori Morrison Bufalo, Marketing Director at Tormach. “We’ve made it easy and affordable for users to perform this upgrade and start getting even better performance out of their Tormach mills.”
The cost to upgrade to the servo motor package is $1,995.00. Additional recommended items including an automatic oiler kit are available for an additional fee.
Later this year Tormach plans to offer a BT30 spindle upgrade package to users as well. This upgrade will allow users to take their ‘M+’ mills to the ‘MX’ level, meaning they will have the servo motors along with BT30 spindles, encoders, and power drawbars.
Rifles can be improved by replacing the stock. Here’s how I re-purposed a Marlin 60 rifle.
