Alf... I used a Bear Creek Arsenal right side charger for a proof of concept build... I wanted to see if I could use the objective length measurements for buffer tube, length of pull and overall length under the ATF4999 document to see what I could come up with, without any deductions ... nothing I can do about the subject evaluation... the right side charger on a 10.5 upper was to eliminate the rear charging handle that dug into my cheek (could have made a right side latch, and removed the left wing), but wanted to use up some Visa points,
the <6" buffer tube and mini buffer/ flat spring from Strike Industries (pricey) was the key...with a vinyl sleeve I can get nose to charging handle, not comfortable but shoot able, and length of pull and overall length fall below the maximum
shot only a 100 rounds or so through it, but not a bobble
Les... Happy New Year to You All
