Bear Creek Arsenal Rifle Length Gas Tube Length

[Inthebushes]

This may be common knowledge, but I couldn’t find it on the old inter web and there was no response from BCA.   It was time for me to replace a 243 Win barrel which was shot out.  Not needing a 4000 yard 1/4 inch MOA barrel like most, and not wanting to spend $600, I bought this BCA barrel for next to nothing.  I read somewhere that BCA uses Armalite length gas system.  The photos below are the BCA barrel (bottom) and the shot out barrel (top).  The top barrel is definitely Armalite length, and the BCA barrel lines up perfectly.  Just info someone might need.
