With a fixed tele-style stock.  I was wondering if you could give me the measurement from the very rear of the but stock on the bottom to the pistol grip.  I'd like to see how this gun will fit me.  I really appreciate it!  Thanks!!!

Since the bottom of the telestock slopes, your measurement is not very accurate....

However, from the base of the telestock buttplate, to the lowermost rear portion of the pistol grip, it is right at 9"

A better measurement, is the top of the buttplate, to the lower receiver, which is 10.5" on mine.

For comparison, a Colt SP-1 with A1 stock is 8.75" from bottom of stock to grip, and 10" from top of stock to receiver.

Therefore, the Bushy M4 should fit a little shorter than the current full stock A2, but a little longer than an early A1.

Thank you very much for your time and expertise!  Good Day
