I watched the SL-15 assembly video but I didn't see any effort made to open up the 3/32 bolt release lever hole for the dowel pin.
In one of my assemblies the hole was very tight and i had to drill it out because i was concerned the receiver would break if I just kept hammering in the dowel pin. Did i miss the drill out on the video?
What have you done? Drill it out? hammer away?
Maybe use a 5/64ths bit so there is still some significant friction to retain the dowel pin?
Thanks
