ADjUSTING THE G28 BUTTSTOCK
The HK G28 buttstock is already installed on the rifle. The stock operates the same as the

standard MR762A1 buttstock and is also adjustable for micro (fine-tuned) length-of-pull

settings and cheekpiece height alteration for optimal use with the scope.

MR762A1 LRP Buttstock Adjustment Procedures
Tools Needed: HK Multi-Function Tool with 3mm and 4mm Allen Wrenches

1. Ensure the MR762A1 is clear by performing a safety check before attempting to make

any adjustments on the buttstock.

The buttstock on the MR762A1 LRP can be adjusted into one of four positions by

depressing the serrated bottom portion of the release lever, located underneath the stock,

and sliding the stock into the desired position (Fig.65).
