Rifle Customization performed by Ken from K&M Aerospace
List of custom work performed on the rifle with pricing:

Standard mod with the slot hole configuration+ charging handle+ upper rail, lower rail and paint – $350
2x 4.12″ side rail – $80
Install side rails – $30
Cheek rest – $35 – very practical and simple mod that allows for a comfortable and consistent cheek weld thus speeding up target acquisition.
Trigger fix – $125 – Probably the best single modification this rifle has seen. It drastically improved the smoothness of the pull and eliminated most of the creep and grittiness that plagued the original setup. Trigger pull has decreased from almost 10 lbs. to an average 6 lbs. 4 oz. on Lyman digital trigger pull gauge. This single mod has completely changed the feel of the rifle.
Gas piston assembly cleaning – $30
Shipping – $25
Total – $675

Overall I have to say that all work performed is of outstanding quality and value and completely changes the look and feel of the rifle. Having previously dealt with a few local gunsmiths that almost ruined rifle’s upper receiver trying to install side rails alone, all my expectations were exceeded by how clean and professional Ken’s work is. I highly recommend his services to anybody looking to add that custom touch to their rifle. Keep in mind that not all services or modifications are listed on Ken’s website, so it is best to contact him directly with inquiries related to any custom work.
