Stupid Question?? (Size of buffer tube)
Hey guys,
I'm interested in installing a new stock on my 15T.
I like the features of the Magpul ACS-L for the storage and higher cheek weld benefit.
Anyhoo, I need to know if our rifles have the "Mil-spec" buffer tubes or "Commercial"?
I'm leaning towards the 'commercial'..............
Could someone let me know, please?
