I took it apart again to measure and it was dry in some places so I used more clr and applied some tw25 to some of the friction spots on bcg. I try a trip to the range Tuesday and take some oil with me.

It is 7 inches.

Just finished my first ar10 in 6.5cm BA 20 in barrel Aero Precision upper and lower with aero internals Leupold 4.5x14 vx-3i Luth-Ar MBA-3 buttstock. Trying to work some minor kinks out but looks good

Ok spring is 11 inches with 28 coils. The buffer is 2.5 inches. I don't have a scale that will weigh it right now. It's too heavy for my powder scale. The tube is an adjustable that is 7 1/4 inches.

all the components in the lower receiver are aero precision, one of their kits. the buffer tube and spring are from sons of liberty gun works. ill post the measurements later when i get home

I only put one box thru it since my range time was cut short. ill have to put picts of buffer tube, buffer and spring later.

have newly built 6.5cm with a 20 in ballistic advantage barrel on an aero precision upper and lower. went to the range to break it in, shoots well, ejects and picks up next round without problems. The issue is that it doesnt lock back on the last round. i can manually pull it back and it locks. i forgot to take an extra mag to check it when i went to range (stupid on my part), Any suggestions to check first. could it be the spring, it currently has an orange spring and buffer (not sure of weight) from sons of liberty gun works. i am running an aero bcg and charging handle. I thought it was oiled well but now im not sure. any suggest to check first?
