View Full Version : L1A1 Front sight question

July 25, 2017, 18:47
So... I removed the front sight post for paint (great ideal right) and neglected to get a measurement "FAILED":facepalm:
Was wondering if there was a standard starting point? Measurement? A Thereabouts?
I really have some good neighbor down range and want to keep it that way :biggrin:

Whenever sights on a weapon are removed (ANY weapon), the weapon needs to be sighted in again. There is no way around it.

A trip to nearest shooting range is in order (what a wonderful excuse!). 'Honey,....I'll be gone for the afternoon, have to sight in my rifle. It'll take a while.' :devil:

Thanks Danielsan
I'll tell the wife that you said it was the rule lol
I was hoping that I could get someone to take a scale and measure what they where getting, just to save time.

Unfortunately, it doesn't work that way. They're adjustable for a reason. With a L1A1, I screw it in about flush with the top of the hole in the gas block sight ears. Just enough that you could see a sliver of light over the top of the sight blade from the side of the rifle through the sight ears. Fire three rounds (never go off of just one) and adjust up or down.

Have fun at the range.

To keep your neighbors peaceful, start at 25 yds to determine zero. Bullet strike should be a little less than the distance between the center of the bore and top of foresight. Adjust as needed. Move to 50 yds and repeat. Then out to 100 yds and finalize everything.
