I can't say yes or no
However, if you don't mind modifying a shroud a little hen if it does not fit it can be made to fit
General concerns of fitting shrouds from a different but similar marker are depending on the type of shroud (full body, part body, barrel shroud etc) body thickness, where the markers body bolts together, and where the shroud bolts together, the positioning of the feedneck, cocking handles, safety, grip and trigger guard
It they match up then no modification required, if they are close then perhaps a thinner bolt will line up, or miss out bolts, drill new bolt holes, dremmel some elements
Here are two I made earlier
These are PCS US5s being fitted to A5 bodykits
The US5 is virtually an A5 without a cyclone
The feedneck aligns with the space for the cyclone so no modding there
For the G36 it was a matter of removing the foresight, widening the shroud for the barrel thread adaptor, tweaking the bolts a little, and the top shroud handle is under a little tension over the US5 body, and redrilling the 'mag well'
Stocks had the same A5 fittings
The Barrett shroud took more work, basically just aligning each part of the shroud, and dremmeling here and there to match the US5 body
