The RS-C is built for the Remington 700 footprint and R700 clones. Compatible actions include:

• Remington 700 (short and long action)
• Bergara B-14 series (extensively tested, drops in without modification)
• Zermatt / Bighorn Arms
• Impact Precision 737R
• Terminus Apollo
• Weatherby 307 series
• Aero Precision Solus (no bedding required)
• Christensen Arms Ridge Scout

Actions with a trigger hanger, such as the ARC Coup De Grace and Kelbly, generally have fitment issues and may require gunsmithing. Contact us before ordering.

The RS-C only accepts actions that use the Remington 700 footprint. It is not compatible with the Howa 1500, the CVA Cascade family, the Ruger American, or the Browning X-Bolt. We do not offer an undrilled blank inlet.

Yes. Our co-founder has personally built multiple rifles with Bergara B-14 barreled actions in the RS-C. They drop in without modification or bedding.

Yes. A short action chassis is the correct choice. Our team has built multiple 6.5 PRC rifles in the RS-C. AICS magazines for 300 WSM work well.

No. Our current RS-C chassis are right-handed only. Earlier ambidextrous versions have been discontinued.

The RS-C uses AICS-compatible magazines. We recommend Magpul PMAG AICS magazines, which feed well with Remington, Bergara, and Zermatt actions.

No. We recommend using S2Delta buttstocks, which are designed to mate with the chassis system. The chassis is compatible with an AR15 carbine tube.

With M-LOK accessories installed, barrels up to 1.15" in diameter fit without interference. Larger diameters, including a 1.25" straight contour, still fit but may require filing or grinding the M-LOK nuts to clear. Barrel diameter right at the receiver face varies by manufacturer, so near the receiver treat clearance as "may need filing" rather than a guarantee.

Without M-LOK hardware installed, barrels up to 1.35" in diameter fit.

• Standard 12" short action forend: no maximum barrel length. It fits 16", 20", 24", and 26" barrels.
• 8" forend (18.5" overall length version): designed for barrels up to about 12.5", ideal for suppressed or compact builds.
• Long action (10" forend): for 7 PRC, .300 Win Mag, and other long action cartridges.

Beyond the ARC Coup De Grace and Kelbly, the Kelbly Nanook is also affected. Some Impact actions have been reported to need clearance work despite the Impact 737R being listed as compatible. If you are unsure about your action, contact us before you order.

The Magnesium Skeleton Buttstock adjusts from 13.25" to 15.75" length of pull. Extension plates with longer screws are included for taller shooters. This range fits youth hunters as young as 10 years old. The buttstock weighs under 11 oz and has a tool-less cheek riser, QD sling swivel sockets, and an M-LOK slot for a bag rider or monopod.

Yes. The cheek riser adjustment screws can be secured on either the left-hand or right-hand side of the buttstock.

Yes, with standard carbine buffer interface stocks only. It does not work with full rifle-length AR stocks. See the Carbine Folding Stock Adapter.

The adapter adds approximately 2" to your length of pull and weighs just under 6 oz. To keep your original length of pull, add our Short Aluminum Stock Tube, which connects between the folding adapter and the buttstock.

S2Delta does not currently offer a 1913 rail option. The buttstock uses a standard carbine buffer interface. Third-party carbine tube to 1913 rail adapters may work, but we have not verified.

No. The recoil pad is a proprietary integrated design, so there is no aftermarket replacement. We have a softer coil pad available for purchase.

Solid steel weights are 12 oz/pair. They come in a QD (quick-detach) version and a standard version. Both are nitride-coated carbon steel, made in the USA. Over-molded Core-Ballast weights are 14 oz/pair.

• Aluminum RS-C: black anodized and Heavy Blue (blue anodized)
• Magnesium Mg-Lite: Gun Metal Gray cerakote

Custom colors and camo patterns are not currently available.

Heavy Blue is the aluminum RS-C in a blue anodized finish. Blue is the only color it comes in. It ships with a black steel tube on the buttstock and M-LOK weight sets installed on the forend. Because the M-LOK hardware comes installed, the 1.15" barrel clearance applies unless you remove the weights.

From time to time, yes. Cosmetically blemished chassis are sold at a reduced price and are fully functional. Check s2delta.com or contact us to ask about current inventory.

Every chassis ships with front and rear action screws, shims, a thumb rest, and thumb rest screws. The shims are for the rare case where action tolerances let the action screws protrude far enough to interfere with the bolt. Slide a shim onto the action screw before installing it, so it sits between the screw head and the bottom of the chassis. This spaces the head off the chassis, so the screw threads less deeply into the action and its tip stays clear of the bolt.

The action screws are 1/4"-28 socket head cap screws in black-oxide alloy steel, available in a 1" fully threaded length or a 2" partially threaded length.

S2Delta specifies the action-to-chassis connection only (action screws, 65 in-lb). The barrel free-floats in the forend, so no hardware attaches the barrel to the chassis. Barrel-to-action torque depends on your action and barrel design (tenon, threads, recoil lug, and action style) and involves headspace, so it is a job for you or a gunsmith.

If you have a specific question, email us and we will walk you through it.

No. S2Delta chassis are designed for a drop-in fit, so bedding is not required. Torque the action screws to 65 in-lb, as listed on the included insert card.

If a product can be added to your cart on s2delta.com, it is in stock and ready to ship. We do not have a backorder feature, so out-of-stock items cannot be purchased on the site.

Yes. The chassis, buttstock, and grip are sold individually. Assembly takes 5 to 10 minutes, and video guides are on our website and YouTube.

It depends on current promotions. During sales on individual components, buying parts separately can cost less. The complete build includes an assembly cost but saves you the build step.

Contact us with photos and your order information. We will resolve it with a replacement, store credit, or a full refund. We stand behind our products.

Contact us with photos. If a component breaks under normal use, we will send a replacement. The magazine release lever is field-replaceable: drive out the pivot pin with a punch, swap the lever and spring, and reinsert the pin.

The magazine latch is intentionally set on the longer side of tolerance so it can be filed down if needed. Try:

• Filing the latch slightly and retesting
• Switching to Magpul AICS PMAG magazines
• Sending us a short video of the feeding issue at info@s2delta.com

We are developing an adjustable magazine latch for future production.

• C-Shape Shooting Bag: medium size for prone shooting and barricades. Works as a front or rear bag.
• Rear Squeeze Bag: compact rear support for positional shooting.
• Bag Rider: attaches to your rifle's buttstock and holds a shooting bag in place while you move, so the bag is already positioned for rear support when you get on target.

All bags ship within 1 to 3 business days from Albuquerque, NM.

The Bag Rider is a buttstock-mounted accessory that secures your shooting bag to the rifle while you carry or transition between positions. When you get on target, the bag is already in place under the stock, with no fumbling to set it separately. It is made for hunters and field shooters who need fast, stable positional shots, and it works with our C-Shape and Rear Squeeze bags. It measures 4.950" long and 0.700" thick, with mounting holes spaced 0.787" apart, and is made in the USA.

Yes. Our bags are used in PRS, NRL Hunter, and NRL22 competitions, and our team uses them on hunts and at the range.

We offer a USA-made 2-point rifle sling in three attachment configurations:

• QD (Quick Detach): QD sling swivel ends
• C.L.A.S.H.: hook-style ends
• Pigtail: loop-style ends

The sling is modular, so attachment ends are swappable. It comes in Black, Tan, and Green. A removable padded shoulder insert is sold separately.

The buckles are a high-strength nylon polymer. We have never had a buckle failure reported under normal use.

The 2"-to-1" hardware transition can rub without padding. The best fix is our removable padded shoulder insert, which fits the QD sling. Contact us for help getting set up with one.
