18″ SOTM5 6.5 CREEDMOOR PRS LITE RIFLE, FAXON MATCH
A large-frame rifle specified one part at a time.
$2,700.00 SKU RFL-M5-65CM-B180-BLK-FX
This SOTM5 is an 18″ 6.5 Creedmoor rifle built on Second of Ten’s billet SOTM5 receivers: a thermal-fitted MOD-0 upper over a 7075-T6 aluminum lower. The barrel, gas system, bolt, recoil parts and controls are each chosen for this cartridge and this role, and each is named below. Receivers and handguard are black.
A note on the name
SOTM5 names the rifle; the serialized part is the lower receiver. MOD-0 names the billet upper fitted to it, here in its no-forward-assist configuration. PRS Lite identifies the stock configuration, built with the Magpul PRS® Lite.
//The Barrel
The barrel is the part of this rifle that most decides how it shoots, so it is the part chosen first. Second of Ten fits the Faxon Match Series 18″ 6.5 Creedmoor barrel in the Gunner profile, and these are the features of it that matter.
//The Handguard
A free-float handguard only helps if it stays where it was put. The 15″ SOT Wedge-Lock M-LOK® handguard is built around that.
//The Case
The barrel comes first
18″ Faxon Match Series 6.5 Creedmoor barrel in the Gunner profile: 416-R stainless, 5R button rifled, 1:8 twist, QPQ nitrided, rifle-length gas. The rest of the rifle is specified around it; the detail is set out above.
A thermal-fitted billet upper
The SOTM5 MOD-0 upper is machined from 7075-T6 aluminum billet to the LR-308 DPMS high pattern, with laser-engraved T-marks and a dry film lubed interior. It is thermal fitted to the Faxon barrel, so the joint between barrel and receiver is an interference fit and not a slip fit.
No forward assist, by design
This rifle uses the no-forward-assist configuration of the MOD-0, with the forward assist bore closed by a threaded forward assist pin. The upper is otherwise identical to the MOD-0FA.
Gas you can set, on a block that cannot move
A RIFLESPEED adjustable gas system lets the rifle be tuned to the load and to a suppressor. On a large-frame 6.5 Creedmoor, where ammunition varies widely, that matters more than on most rifles. The gas block is pinned to the barrel with a steel coil spring pin, in line with the Bombproof by Design™ philosophy.
A bolt built for 6.5 Creedmoor
The Toolcraft AR10 6.5 Creedmoor bolt carrier group, black nitride, with a double-ejector bolt. Second of Ten laser engraves the bolt “6.5 CREEDMOOR” so it cannot be mistaken for another large-frame bolt on the bench or in a parts bin.
Caliber marked on the cover
The ejection port dust cover is engraved 6.5 CREEDMOOR, so the caliber reads at a glance with the cover closed.
A two-stage trigger, left as made
LaRue Tactical MBT-2S two-stage trigger with a curved bow. It breaks crisply at 4.5 lb (2.5 lb first stage, 2.0 lb second) with a smooth and positive reset. An additional heavy trigger spring that raises the pull to 6 lb is included with the rifle. Second of Ten does not stone, polish or alter sear engagement surfaces.
Controls on both sides
Ambidextrous bolt release, with a paddle-style oversized bolt catch on the left and Second of Ten’s own serrated release button on the right. Extended left-side magazine catch release with a right-side button. Breek Arms WARHAMMER Mod2 charging handle with oversize latches on both sides.
A selector you can set to 45° or 90°
The Radian Weapons Talon® 45/90 ambidextrous safety selector runs as a standard 90° selector or as a 45° short throw by rotating the shaft 180° inside the lower. It is installed and configured at 90° and can be reconfigured by the end user.
A buffer that takes energy out
A KynSHOT RB5005 hydraulic buffer with a Tubb Precision flatwire rifle-length spring, in an SOT SR25/A5-style 9-position receiver extension on a nitride-finished castle nut. Every other buffer moves energy around inside the rifle; a hydraulic damper converts some of it to heat. KYNTEC builds it in 17-4 stainless, rated −30°F to +150°F, for AR-10 and A5-length tubes, and the claim with real weight behind it is reduced bolt bounce.
Tension where the halves meet
The billet lower carries an upper receiver tension screw, a threaded bolt catch pin and a rear takedown detent spring with set screw, with Battle Arms Development enhanced AR-308 steel pivot and takedown pins.
Furniture for shooting from position
Magpul PRS® Lite stock, with length of pull and comb height adjustable, and a Magpul MIAD® GEN 1.1 TYPE 2 grip, with taller backstraps for 7.62×51 receivers, both in black.
//Inspect It Yourself
This rifle has a zoomable inspection page showing both sides of the rifle as built, so the markings and machining can be read from the photograph instead of taken from a spec table. The serial number is blurred; no other marking is altered.

//Notices
Set the gas for the load
The adjustable gas system should be set for the ammunition in use and reset when a suppressor is fitted or removed. A setting that suits one load is not necessarily right for another.
The selector is set at 90°
The Talon® 45/90 selector ships configured as a standard 90° selector. It can be changed to a 45° short throw by rotating the shaft 180° inside the lower receiver.
