I ordered this knowing it wasn’t recommended for the nexus but wanted to test it out anyways. I also ordered the nexus scar barrel and both shoot to the left.
This barrel in particular is very snug. It’ll fit in the nexus with some force, but good luck getting it off. Hence, not recommended for the nexus.
As far as performance goes. It’s equivalent to the nexus scar barrel they sell. Both were consistent in trajectory while going left. Personally I don’t like having to compensate for it.
