Description
Army Armaments G17 GEN 4 Rear Sight (A-205)
This is a replacement rear sight from Army Armament, part code A-205, identified for the company’s G17 Gen 4 gas blowback pistol. It is a small external part that lets you replace a lost, broken or worn rear sight and get your pistol back to its proper sight picture.
Army Armament is known for affordable gas blowback pistols, and having spare parts available keeps those pistols in service for longer. A rear sight is easily knocked when holstering or crawling, so it is a useful spare to have.
What it does
The rear sight sits at the back of the slide and works with the front sight to give you a sight picture. If it is missing, loose or damaged, aimed shots become much less predictable. Fitting a fresh sight restores a clear notch to line up with the front post.
Rear sights on G17-style pistols are usually held in a dovetail slot across the slide. Fitting can be tight, so take care to centre the sight and avoid damaging the slide finish.
Fitting tips
Before removing the old sight, note its position so the new one can be set in the same place. Use a non-marring punch or a proper sight pusher where possible, support the slide on a soft surface, and work slowly. After fitting, check your point of aim at a known distance and nudge the sight left or right if needed.

Compatibility
Identified for the Army Armament G17 Gen 4. Parts are not always interchangeable between makers or between pistol generations, so confirm the model and mounting of your pistol before purchase. If in doubt, compare the photos with the sight on your slide.
Care and maintenance
Check that the sight is secure each time you clean your pistol, as a loose sight will shift your point of aim. Wipe it with a soft cloth and avoid solvents that could damage any painted dots or the finish.
Store the pistol in a padded case or holster that does not put pressure on the sights. Keep the rest of the pistol maintained as usual: a drop of silicone oil on the magazine seals and slide rails helps everything run smoothly.
