Most Helpful Positive Review Really good, not great...
I do like this fsp, as it does increase contrast when using buis against a dark background. The glow is never going to be too bright, even in a pitch black cave. It seems like the tritium is already old compared to pistol night sights,but I think the insert is just really small to keep the sight pos...

Most Helpful Negative Review Bad manufacturing process
I purchased the yellow spike model and then inserted into a red lion front sight for a keltec sub 2000 Gen 2 / 40 cal. Took it to the outdoor range to dial it in. With less then 50 rounds down range, the yellow insert fell out, whereabouts unknown. If these inserts come out this easily I would recom...

Not as bright as real tritium sights

by Josh, Verified Owner from GA, United States Written on May 7, 2025
Fits correctly into a standard mil-spec front sight post. The shape and color are accurate to the picture. The "Luminescent Contrast Stripe" works but only after "charging" it for a couple of seconds with a bright light aimed directly into it at close range. So it's "luminescent" in that way, and is really bright after absorbing light from another source, but don't expect to be able to use these in any real low light scenario like a set of TruGlo/Tritium sights.

The colored front post can help for some people in acquiring a sight picture, so I recommend it for that, but if you're looking for a something for real low light scenarios, this is probably not it.
Pros:
  • fit correctly, nice shape and color
Cons:
  • not as bright as expected
Would recommend: Yes

should do the job with considerations

by someone, from SD, United States Written on December 10, 2023
Did just fine in the a2 post. Definitely grabs the eye when you get behind the sight. Only thing to worry about is if you don't have elevation on the rear peep then your adjustments will be vary course do to the design, it's made and designed well but should be considered.

A shot in the dark

by Vernster, Verified Owner from CO, United States Written on March 22, 2022
Don't confuse Blitzkrieg with being a WW2 term. Look at it as a battle prozen name of fear. This sight post during the day is an apparent visual aid, and at night, it's a beacon of business. When I bring it in, I just say "hello". Mounted on an offset, so when the battery dies on my night vision, I still have a shot in the dark. Thanx OpticsPlanet.

Blitzkrieg spike yellow front post

by ChrisK, from WA, United States Written on June 18, 2020
Love these front sight posts, have the yellow one on two of my ARs. Really helps me pick up the front post against darker backgrounds. I live in the Pacific Northwest, it’s often dim and cloudy and I’m shooting against dark backgrounds. Great product!

Awesome front post

by Mr.45-70, from CO, United States Written on March 15, 2020
Installs super easy with a front sight tool, looks and fits perfectly on my retro build with A2 front post. Paint is bright and on both sides, and the point it comes to is very fine and accurate. A great upgrade for the money.

Not item pictured.

by Daniel, Verified Owner from NC, United States Written on March 13, 2020
Ordered Spike front post with tritium dot. Pictured is a Trijicon sight, shipped an off brand sight to my home. Seems to work, still has tritium dot. But it is in fact a knockoff of the Trijicon pictured. Such a let down
Pros:
  • works
Cons:
  • Sent off brand sight in place of Trijicon
Best Used for:
  • range toy
Would recommend: Yes
