Will it impede function other than looking off to an expert?? Getting them in without the proper spanner was a PITA and getting them out after being impacted with Tung oil isn't going to be pleasant.. Also, I seem to match many of the pictures of 1903A3s on Google. I Googled images of 1903s before I set the pins. The "new" production advertized by Aim Surplus has the bolts inserted left to right with the nuts screwed in on the bolt/right side of the rifle.
