KRG C-4 Chassis Review

Estimated studying time: 8 minutes

Established in 2010, Kinetic Analysis Group (KRG) has change into a frontrunner in rifle taking pictures innovation. Their bolt-action chassis lineup provides one thing for everybody—from finances plinkers to severe long-range rivals. The Bravo chassis contains what KRG sees because the necessities, delivering a secure, budget-friendly platform. It’s an incredible entry level for these transitioning from a conventional rifle inventory to a chassis system. Greater up the road are the Echo, X-Ray, and Whiskey-3 fashions, every with distinctive options that set them aside. On the prime sits the C-4 Chassis, designed to face head and shoulders above the remaining by way of efficiency and functionality.

After getting my palms on one for some time, I used to be in a position to put that declare to the take a look at.

First Appears to be like

KRG’s C-4 Chassis first caught my eye at SHOT Present a few years in the past. Designed with enter from aggressive shooters and machined from a single block of billet aluminum, the C-4 stands out from the smoother, slab-sided forends frequent to most chassis designs. As a substitute, it integrates a stout cross-section of accent rails, giving it a beefy look that’s each purposeful and attention-grabbing.

The 16-¾” forend includes a full-length ARCA rail on the underside, with M-LOK slots down the middle. Alongside each edges, machined holes assist Actually Proper Stuff’s RRS-Lock merchandise. Perpendicular oval slots alongside the rail match KRG’s proprietary 𝚫-Lug (Delta-Lug), a push-button system for quick, safe accent relocation alongside your entire rail.

Either side of the forend contains 5 M-LOK slots machined into raised, Picatinny-like accent rails. I say “Picatinny-like” as a result of, whereas the outer form mimics a regular pic rail, the cross-slot ends are closed and sized just like the lugs on KRG’s present ARCA-based 𝚫-Lug. The chassis sides are additionally drilled and tapped for KRG’s bolt-on equipment.

For-end Particulars of the C-4 Chassis

When ordering the chassis, you’ve gotten the choices to select from one among three barrel shrouds: a full-length, an optic inlet, and an prolonged optic inlet shroud. KRG’s C-4 webpage has a really thorough infographic that aids in choosing the proper shroud on your rifle. The forend and shroud can accommodate any barrel profile as much as a 1.25” straight cylinder. The highest of every shroud is drilled and tapped to just accept a picatinny rail that matches its prime size for mounting evening imaginative and prescient, lengthy vary prism optics, or different equipment. 

Inlets and Magazine Properly

Shifting again from the forend, a rugged barricade cease is machined into the entrance of the journal properly. The magazine properly itself is outsized, and options an adjustable spacer to effective tune its size. Two leaf springs contained in the magazine properly will be bent out and in to regulate the stress in your AI or AW journal of selection.

The magazine top itself will be modified simply by adjusting the screws on both aspect of the ambidextrous magazine launch. This function was particularly of curiosity to me, because the Seekins Precision HAVAK motion I deliberate to make use of would require the journal to sit down decrease than a regular Remington 700 would, regardless of it being thought of an R700-type design. So far as inlets go, the C-4 will be ordered for Remington 700 Brief or Lengthy Motion, in addition to the Tikka T3 CTR and T3 Brief Motion(AICS mags solely).

C-4 Motion

When mounting the motion, the C-4’s inlet is radiused to match. The recoil lug pocket is spacious and suits even the biggest aftermarket lugs. In case your motion makes use of a set off hanger, there’s loads of machined area to accommodate most hanger choices out there.

When ordering, you’re given the selection between a regular, outsized, or thumb shelf grip. The grips are polymer and have rubberized inserts. Every choice is ready simply shy of 90°, which retains the hand in a impartial, relaxed place whereas firing. The thumb shelf grip choice not solely has the thumb shelf within the higher a part of the grip, but in addition has an adjustable finger relaxation to attenuate detrimental set off inputs. 

Buttstock

Shifting rearward, the chassis’ monolithic design means there’s no folding buttstock, however it does add rigidity from entrance to again. The buttstock is absolutely adjustable with out instruments. Aluminum knobs management pressure for the size of pull, cheek riser, bag rider, and buttpad top and cant. Size of pull adjusts from 13” to 14-⅜”. If extra size is required, KRG’s commonplace or heavy LOP spacers will be stacked below the rubber recoil pad.

The cheek riser is available in two choices: enhanced or rubber overmolded. It adjusts as much as 1.1” above its lowest place. If the cheek pad sits too far ahead or again, you possibly can reposition the connecting rods with an allen wrench to suit your choice.

An ambidextrous anti-rotation QD swivel cup is constructed into the buttstock. There’s no ahead QD cup, however the forend has a number of drilled and tapped holes and M-LOK slots. You may mount the cup wherever it most closely fits your setup.

Heavyweight

The burden of the chassis alone is 6.3lbs. KRG has a variety of metal weights that may be bought individually and mounted to extend the general weight and stability of the taking pictures platform. The mannequin I examined had one of many 1.13lb inside forend weights, in addition to two of the three.7oz rear weights, bringing the chassis as much as 7.9lb. Add in my HAVAK motion with a 24” M24 Contour 6mm Creedmoor barrel, SilencerCo Omega 300, and Nightforce ATACR 7-35x56mm in a Warne Skyline one piece mount, I used to be toting round a hefty 20.2 lbs rig absolutely loaded.

Remaining Ideas On the C-4

Taking an already soft-shooting cartridge just like the 6mm Creed and firing it from a rig this heavy was a pleasure. Whether or not on a bipod, tripod, or barricade, pictures might be taken at distance with ease. The chassis balanced properly, and the inflexible 16-⅜” forend had zero flex, even when loading weight anyplace alongside its size. The built-in ARCA dovetail provided a large, secure firing platform and the built-in barricade cease was one of many extra aggressive designs I’ve used over the previous couple of years. Vary days are sometimes made higher by good firm.

The absolutely toolless changes within the buttstock enable for fast and simple changes to comfortably match anybody in our group. This feature-rich chassis comes with a price ticket to match ($1,999.99 MRSP). It’s designed and constructed for the intense long-range aggressive shooter. In comparison with the remainder of KRG’s choices and some rivals, in my thoughts, it really does set itself above the group.
