Thread: .30BR Rem 788 Chassis build

I was also handed a Krieger 1-13" twist .308 win 30" Palma match barrel to use on the donor action.

I stripped the rifle down removing the barrel and the trigger (which was in for some serious mods later) I measured up all the major action dimensions to see if I had the required materials on hand.



When I made my last CZ 527 Grendel chassis I actually cut 3 blocks of alloy to length and had turned and threaded them in the 4 jaw chuck to except a buffer tube at the same time to save on machine setup time.








In hind site it was a little over zealous of me to pre-cut them all to CZ 527 length because it was a little too short to fit the 788 action. However I devised a plan to fix that that later that still saved on 4 jaw set up time on a new piece of billet and machining time.














The next stage was mocking up and marking out. It was obvious at this stage that the billet was about 30mm too short to capture the recoil lug at the front and leave enough room to mount the pistol grip. The trigger was also going to be an issue as it the blade is long way back and wasnt long enough to protrude from the chassis. I was tossing up whether to continue here or go back to the drawing board and design a new shape that would work that would have to be machined out of a much larger alloy billet.
Here it is laid out with the CZ 527 Grendel build.
