I have been searching a bit with no success.
I am looking for the picture or thread that shows M4 feed ramps and regular ramps on barrels and receivers and which ones work together. I am also looking for the picture that shows the parts differences between an M16 and an AR15. The last query I have is when did Colt start putting FA carriers in AR15's, specifically Match Target models, HBAR's, Competition HBAR's etc. |
