16″ Samurai Series Maruni Edition 違い矢 RECCE Rifle SOT Custom Shop build · right and left side · drag to pan, scroll to zoom

CONFIGURATION SHOWN: a Sharps Bros. upper receiver with a laser engraved nickel plated ejection port cover carrying the Maruni Chigai Ya mon and the caliber marking, a 16″ stainless steel barrel in 1:7 twist on a mid-length gas system, an MB15 stainless steel muzzle device and a blue PVD bolt carrier group, with Brazilian cherry M-LOK rail covers on nickel plated fastening hardware — paired with the Maruni Edition RECCE rifle lower receiver. Right side shown — 将軍 (shōgun) on the magwell, the MDL. SHOWDOWN · CAL. MULTI rollmark, the nickel plated ejection port cover and the 違い矢 Chigai Ya handguard marking.

* Sharps Bros. manufactures the receiver; Second of Ten is the builder of record. The receiver is manufactured, rollmarked and serialised by Sharps Bros. of Eugene, Oregon as a 7075-T6 billet SHOWDOWN, and Second of Ten claims none of that engineering. Samurai Series and Maruni Edition name the complete Second of Ten rifle built on it — the barrel, the muzzle device, the bolt carrier group, the controls, the furniture and every applied finish are Second of Ten’s selection and work. The rifle is the whole assembly; the serialised part is the lower.

The steel through the handguard is the barrel, not the rail. The 16″ barrel is stainless, left bright, so it shows through every M-LOK slot along the handguard. What reads as a silver-flecked rail in these frames is the barrel behind a black handguard. The Brazilian cherry rail covers ship with the rifle but are not fitted in either frame — the slots are open on both sides — so that row alone cannot be checked against the photography here.

This is the lower from SOT-WEB-SAM-LWR-012, assembled. The receiver photographed here carries the same serial as the Maruni Edition RECCE rifle lower on its own inspection page — one receiver, two states. The trigger, the bolt catch, the magazine button, the grip and the Reptilia stock all match that page; what is new here is the Sharps Bros. upper in front of it.

The menpō mask is finished by hand, so no two are identical. The face, the gilt scrollwork and the white teeth are applied and blended by hand over the Cerakote® base, and the blue is graded rather than flat. Highlight placement and the exact break of the burnished panels will differ from the rifle photographed here. That is the nature of the work, not a variance to be corrected.

The crest runs the length of the rifle. The Maruni Chigai Ya mon — crossed arrows in a ring — is laid in maki silver foil on the grip panels, laser engraved into the nickel plated ejection port cover beside the caliber marking, sprayed in silver Cerakote® across the Reptilia stock as a field, and printed on the handguard beside the edition name. Four scales, four methods, one crest — which is what carries the edition rather than any single component.

The two sides do not repeat each other. 侍 (samurai) is carried on the left of the magwell and 将軍 (shōgun) on the right. Read one side and you have only half the piece — which is the reason this page shows both.

Nothing in these frames is retouched except the serial. The serial number is masked on the left-side frame. The manufacturer and address rollmarks are left exactly as struck, and no mark, blemish or tool witness has been removed.
