Yes, many people have done PDI VSR-10 builds with the precision chamber.awagg said:PDI is confusing, because they try to make it seem like all their parts are proprietary, but in truth, they aren't really. All PDI pistons work with all PDI cylinders. Same with springs, spring guides, and cylinder heads. Their PDI hop up chamber "only" barrels are just AEG cut, but really well made, as goes for most/all of PDI.
The thing I'm still trying to figure out is "does the PDI cylinder head fit with the stock TM (or precision) hop up chamber?
