Geissele cut rifle barrel

Recently won a .22 cal Geissele barrel blank. Unfinished, mtu contour. Anyone have experience with these? I have seen very little about them online.
In the semi auto forum people seem to really like the Geissele cut rifled AR barrels. I assume they are the same blanks as you won but just have a gas port drilled out, correct profile to receive a gas block, etc..
 
@BenE picked one up off the prize table and we cut it here. He can give you his experience with it at the range. When I looked at it the interior was nice, like all things Geisselle it was well made. He did make a comment about barrel life but said it shot well, I'm sure he can fill you in more.
 
I purchased two of these back in 2023 when they were only offered in 6mm. I got a screaming deal at the WAR two day match and figured why not. Bore scoped both barrels, looked great. Chambered both of them in 6 Dasher. Ran the first barrel at 2840 with Berger 105’s. Barrel shot great for about 1500 rounds when it started holding on to excessive amount of copper. By 1700 rounds it struggled to hold a water line 700-1000yds. By 1800 rounds I pulled the barrel. The other barrel was spun on this year but I haven’t shot the rifle enough for longevity claims.
