AR-15 Dual Post Rear Sight Modification - Good Smith

[DustyRusty]

I have a AR-15 competition service rifle that I want to have the rear sight pinned.
It is the fixed carry handle version.
Has anyone here had it done, know something about the results?
Anyone have a favorite smith for AR's?

I'm not familiar with that procedure. Why is it done?

 

[DustyRusty]

A steel pin is installed vertically, rearward of the elevation drum. One end is secured and the other floats within the vertically movable sight body. Its purpose is to prevent any non vertical movement of the sight body. Its a 600-1000 yard accuracy thing like floating the barrel etc.

I learned something new! That's a slick trick

Better for competition Service Rifle in 2024 than to pin the rear sight is to swap the upper, ditch the A2 altogether, and stick on a scope.

Are optics allowed in service rifle now???

Yeppers, took my White Oak A2 upper with the pinned rear sight apart and sold the upper and used a Aero flat top upper to mount a budget Vortex Ranger 1-4X for club level Service Rifle competition.
It's a fun to shoot configuration and with a QD mount I can still use my MaTech rear sight, while no where near as good for competition it's more than adequate for good iron shooting.
OP if you're bound and determined to get an A2 service match upper I highly recommend White Oak mine was excellent but sucked trying to compete even at the club level against the scopes.

Do they at least put scopes in a different division or is it even Steven?

Same class - up to 4.5x optics are included in the standard ruleset since 2016 season (passed '15).

I'm all for pinning the rear sight, but for the performance return on investment, swap for a flattop upper and stick on an optic.

There are very specific rules on what scopes are allowed. As was mentioned, 4.5x magnification is the max.

I have an upper with a scope but still prefer to shoot the iron sights. I have been doing it for a while though…

 

[DustyRusty]

Irons and scoped in the same class? This is lost on me.
Irons are in a class by themselves. Like a vintage rifles are in a match by themselves.
Things change I guess. Like shooting from the supine position was a thing, way back when in 1870

Or “The Creedmoor Position” when shooting long-range silhouette shots.


This guy has a leather blast guard for the B/C gap gasses. I tried this once with a 4” Model 19 .357 without such a guard.

That was one shot too many. I just about hit what I was aiming at, but I was picking denim strands out of the powder burned gash on my calf for days afterwards.

Stay safe.

A lot of hold-outs don't like the change, but Service Rifle as a sport is dying, and we can demonstrate multiple instances of issued optics in contemporary Service Rifles, so optics were adopted as standard fare. Personally, I quit shooting SR a long time ago, largely due to culture which drove me to focus on other disciplines, but since then, I've had an itch to go back and shoot them again, and I live only a half hour from a range hosting regular practices and matches - but my eyes have declined to the point I really couldn't even make a game of it until the Optics allowance was added in 2015. It won't be my primary competition type any time soon, but it's kinda fun to go out and toodle around with SR occasionally. Biding time to replace my current barrel with a faster twist though, and a non-threaded muzzle.

I suck with irons and optics, but IMO shooting longish range with military iron sights should remain a separate class at least. I see the reason for optics and I see the reason for allowing red dots in bullseye. But I think the people who put in the time and can develop the skills to shoot well with irons should be rewarded rather than penalized. I guess it’s just like any sport. The rules determine the game. But it still makes me sad.

However I’m not out there doing it so my opinion doesn’t hold much weight LOL

At my first barrel change, I went from no flash suppressor allowed to flash suppressor installed. (Coolness factor)
The original Douglas barrel was shot. The 2nd barrel was a Keiger and I began shooting 69gn bullets fast at 200 yards offhand. Wow what a difference.
They were thru the target before I heard the rifle go bang.

but my eyes have declined to the point I really couldn't even make a game of it until the Optics allowance was added in 2015.

I have a bag of safety glasses at 1.0 to 2.5 power. I find the one that matches the firearm and make note of it.
I guess those are my optics now.
My AR service rifle will come out this spring and shoot off the bench.
