I attended the New Shooter High Power Rifle Clinic at the Illinois State Rifle Association in Bonfield, Illinois yesterday. My uncle and I took the course, both of us shooting our Rock River Arms Standard A4 rifles. What a great learning experience and group of people. I have never shot competition before, so I thought I should try a high power course.
Sometime before the course I installed a KNS precision .052" front post. The smaller front post is really nice, especially because I'm used to using the NM .062" post on my M14. With the shorter sight radius of the AR-15 rifle, I think the .052" post most approximately provides a similar sight picture. It was hard to shoot a good score while zeroing the front sight at the same time, hehe.
Also, I installed a David Tubb chrome silicon spring to eliminate the "sproing" sound during fire. The Tubb buffer spring though; I hate it. The Tubb spring was a bear to install over the buffer shoulder and makes the action feel like it's binding; which it is, because the mag wasn't always locking back after the last round. I put my USGI spring back in and all was 100% again. Maybe I will try the Damage Industries spring; I've heard nothing but good things about them.
I was disappointed to hear that my Matech OGU83 sight is not match legal. I love the sight. And considering it is one of the most, if not the most widely used rear iron sight in the U.S. military today, I think it should be legal.
Well considering that I was fussing with the front sight and trying to sort out my sling usage, I hope I did alright. But, then again it was a class so that's a good place to sort things out.
