Warinterest HK416 original barrel length

Howdy y’all,
Hoping that someone out there has one of these blasters and can provide the length of the barrel it came with.
Thank you in advance

29cm is the original barrel length in these.

Recommend you use a 30 or 31cm replacement, the design of the handguard means you often end up catching the edge of the barrel when putting it back on and pushing it further into the T-Piece, if you push it too far it falls into the inside of the outer barrel.
