I just had a thread locked talking about these sights so I would appreciate it if this one was kept civil.
I just took my rifle with the tech sights out for the second time. Sighted it in for 20 yds. since its so windy today. 20 yds. is the first time the bullet crosses the line of sight for a 50 yd. zero. I was rested in good solid rest on a good solid bench. I was having some issues with horizontal stringing and could not figure out what was going on.
This target was at 20 yds. The right side group is Wolf MT, which is standard velocity. The center is Remington CBee, the new subsonic rounds that I recently posted on. The left two targets are Federal Automatch, which this rifle has always liked.
You can see that the HV rounds were stringing horizontal pretty badly. The CBees were getting blown around some, but the cause could have been the same. Only the wolf grouped decent.
When I got home I found out the front sight is really wobbly. Very loose threads. It actually has about .013" of movement from side to side. If my math is correct, with the 23" sight radius, that represents approx. 2 MOA of movement.
I have wrapped the threads of the front sight in teflon tape. It took 4 full wraps to get it tight enough that it won't wobble. Its still easy to turn.
I had some issues with the finish on the front sight. Pretty ugly in my opinion. Doesn't affect function at all, but it does not give me warm and fuzzy feelings when the sights cost $75 delivered. I expected more. Didn't know they were made in Taiwan either.
This is a picture of the rifle with the sights installed.
I will let the reader be the judge. I am thinking about going back over and doing some more shooting. Even in this wind I would be able to tell if the horizontal stringing was me or the rifle. I thought it was me until I found that sight wobble. I am not that terrible a shot.
