Cheek Riser for HK417 / MR308

Designed for seamless integration with the Heckler & Koch HK417 / MR308 / MR762 OEM adjustable buttstock. Intended for professional use.

• Tool-Free Installation: Quickly mount and remove without tools.
  
  
• Two Fixed Positions: Adjust the cheek riser in either a forward or rearward position by rotating the indexing spacer located on the underside of the stock.
  
  
• Height Options: Available in 8mm, 12mm and 18mm.
  Custom heights can be manufactured upon request.
  
  
• Important Compatibility Notice: Due to the long charging handle travel of the HK417 / MR308 platform, the charging handle may contact the cheek riser when the stock is adjusted to shorter length-of-pull settings. If you typically run your stock in position 1 or 2 from the fully collapsed position, this product is not suitable for your setup.
