SMITH & WESSON - Sight Blade Kit, Rear, .146", for S&W K,L,N Frame Blue

Ordered S & W parts and had them in 4 days. USPS had to do a good job job but Brownell’s had to do a good job getting them to postal service quickly.

I've alway found Brownells to have top quality products and their customer service is exceptional.

Once upon a time I bought just the sight blade and realized afterward that I need the nut and bolt to complete the replacement. So, I ended up just buying this kit that has everything. The sight blade was a lower profile than my factory S&W 686, but it was still with the adjustment range of the target sights, so I was still able to get it zeroed just fine. Fairly easy install and you don't need the special 2-Pronged spanner wrench to complete the job, I bought them and didn't even use them.

This made a great improvement to the overall curb appeal to a retired police revolver with a dog eared sight. Mine has a very nice white outline, perhaps better than the original sight. Perhaps S&W saw the other feedback and improved? Anyway, though not totally necessary, the spanner bit and staking tool do make life easier. Measuring the existing sight it a good way to confirm you are ordering the correct replacement. Identify the location of the detent plunger in the side of the screw head prior to removing from sight body so you can contain them, and confirm the nut wont turn on the screw to verify it is fully staked.

My S&W 617-6 with a 4 inch barrel shot to POA at 10 yards with many types of ammo but rear sight was cranked all the way down. I wanted the option of going lower with the sights. The rear sight, measured with a micrometer, was .146 from the factory. (Not .136 as stated in many sources on the web.) Purchased the S&W .126 white outline rear sight blade kit and installed as shown on the video at Brownells website. I gained several more clicks of downward vertical adjustment. YMMV Functions as if it was installed at the factory.
