Thread: Olympic AR15 .22lr and .17 Mach2 upper

Very Rare and accurate If you want to play with it or collect it











Works excellent in 22LR blows a case rim out or bulges a case in .17 Mach2 2x a mag if dirty works best with a very clean chamber
Needs bolt mass to be higher in .17 Was gonna make bolt inserts of different mass to compensate but never followed through just shot it in .22

I have never seen another for sale This has manual and 4 mags, Black Dogs work also
They said they (oly) stopped production after very few made and just made them in .22
I kept it to someday work out the .17 but I've got .17 Mach2 Rugers that are doped out and use them for sage rats.
