Expected life of a flash hider
I have a A2 type extended flash hider on my 14.5 middy and it appears to have developed a horizontal crack at the far end by one of the open sections.
I've owned the upper since it was new and it has not been beat up, it was purchased in 8/2010 and it has approximately 1400 rounds thru it.
I have not contacted the builder yet as I wanted to make sure I did not have an unreasonable expectation that it would last the life of the barrel absent unusual damage.
Please let me know if my expectation was is in error.
