Remington 700 X-Ray Chassis by KRG

X-Ray Chassis Forend (Generation 4 Chassis):

• Polymer for light weight and to eliminate heat transfer to/from the shooter's hand
• M-LOK slots on sides for mounting flexibility
• Mounting holes at various positions will take L2 Picatinny rails, Tripod Mount, Barrier Stop, etc
• Access hole for action mounting screw, so you can remove the action without removing forend

"Backbone"/Chassis:

• Aluminum backbone runs to tip of forend for maximum stiffness and modularity
• Utilizes radius bedding, which is CNC'd into aluminum backbone for consistent contact between action and chassis
• Can accommodate most large aftermarket recoil lugs like the Badger Ordnance lug without any or with only slight modification
• Accepts the Whiskey-3 gen 3/4 Spigot Mount
• Designed for 5 or 10 round AICS magazines (with front spacer plate only in Remington 700 unless you have a modified action)
• Barrel contours accepted: 1.25" for 4" in front of action face, then 1.20" straight to end of forend. A 1.25" straight cylinder barrel will fit but KRG feels that the clearance is too minimal. They recommend a varmint or medium palma contour to keep proper balance

Trigger Guard/Mag Catch:

• Similar in shape to TRG trigger guard. Made from reinforced polymer for added strength and less cold/heat transfer to the shooter's hand
• Will accept the new X-Mark triggers and nearly all aftermarket triggers but some aftermarket triggers may require modifications to the trigger or chassis
• Mag catch is the same as the Whiskey-3 but the catch extender button is an optional item

Cheekpiece/Handgrips:

• Cheekpiece infinitely adjustable within range (1" travel)
• Cheekpiece can be quickly removed and re-installed, uses a clamp and thumbscrew design
• The thumbscrew can be positioned on either the right or left side of the chassis
• Includes a simple feature to make the cheek piece return to the exact height you set it
• Cheekpiece can be moved forward or backward with one alternate position
• Cheekpiece made of polymer to not transmit heat to or away from your face
• Small grips are standard fitment.  Larger grip size is available as an option.

Length of Pull (LOP):

• Adjustable with spacers in 3/8" increments with nearly 2 1/4" of adjustment range
• LOP range varies slightly between versions but is roughly 12.7" to 15" (longer length is possible with additional optional spacers)
• X-Ray's include the KRG 1-3 LOP kit which includes 3 spacers and the hardware to mount either 1, 2, or 3 allowing a max LOP of about 13.8"

Buttstock:

• Single piece body made of reinforced polymer material
• Heavy internal ribbing provides great strength
• Mounting points for external QD cup or for the KRG Sling Loop/QD mount on either side
• Built in thumbshelf for same-side-thumb-grip shooter
• Entire buttstock assembly can be used on Whiskey-3 if you should desire

Buttpad:

• High quality KRG recoil pad with Tool-less height and cant adjustments
• Adjusted with hex wrench
• Buttpad is Remington 700 pattern so user can install aftermarket pre-fit pads

Mounting features for slings, monopods, etc:

• Buttstock has one position on each side for external QD cup and one position on each side for Sling Loop/QD Mount (optional accessories)
• Buttstock includes mounting points for an optional bag rider/butthook or MOE L2 Picatinny rail
• Harris bipod stud included on forend
• Spigot Mount can be added to front of chassis
• Ambi QD sling plate can be mounted and provides 3 positions for QD sling or HK hook sling attachments (optional accessory)
• All X-Ray stocks come with one MOE L2 rail

Materials/Finishes:

• Most aluminum parts are hard anodized Type III
• All fasteners are stainless steel, some with black oxide coating, some without
• Steel parts are salt bath nitrided or stainless steel
• Grip panels, forend, buttstock are injection molded reinforced polymer
• Weight 3.0 lbs without magazine
