As per the description:

*Please Note: Chrome-lined chambers cannot be cut & may not headspace to your bolt/receiver


Has anybody mounted one of these Bbls, and, if so, did it headspace properly?

Never used a chrome lined M1 Garand barrel. But I did mount a Criterion Chrome lined M14 barrel with out any problems on 25xxx SAI MIA utilizing a unissued TRW bolt.
M1 Garand bolts vary in length with in the spec. SA-2, SA-19 and SA65 bolts seem to be on the long side of spec. Winchester bolts can be anyplace with in the spec from long to short. The trick is finding a bolt that will headspace with the barrel not knowing before hand what the headspace will be. If you have spare bolts and headspace gauges you can check your bolts in a known barreled action that is with in spec. I marked my bolts per length after checking them this way.

Since you can't ream the barrel you will have to swap bolts until you find one that will head space properly.

Shortest to longest bolts:

WRA
-12SA
-14
-17
-19
-2
65 series

Headspace really is important . . .

Sounds like a good project Bbl. for the CMP Advanced Maintenance Class.

... or for someone w/ a lot more spare bolts that me.


A chrome-lined bore, for a field rifle here in the Great State of Louisiana, would be a nice thing to have.

I always thought that stellite was a better way to go in barrels. We used this material in nuclear reactor research. It’s tougher than woodpecker lips.

Stellite has been used in chamber and throats of full auto weapons to prevent throat erosion. The bore of these barrels are chrome plated. M60 MG and .50 cal. BMG are examples utilizing stellite inserts.
