Was hoping to tart up my E&C M16A1 with this set, alas the outer barrel didn't *quite* fit, would've just needed a bit of sanding.  Also the shoulder just behind the gas block/front sight is too small to lock an A2 round handguard cap in place, only holds an A1 triangular cap.  I took it out the packet, tried fitting, did keep the barrel nut/delta ring assembly (this listing includes the E&C part) then put it all away in the bag again.  No other usage.

Outer barrel is way nicer than the E&C otherwise and the triangular handguards are literally in a different galaxy compared to the E&C ones I had.  These ones are sturdy and extremely nicely moulded, with heatshields and the two halves fit with each other/on the barrel absolutely perfectly.

Price is all-in, ONO.
