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...

small upgrade with good value

by Ray, Verified Owner from UT, United States Written on June 7, 2026
If you run BUIS or irons then these are a good way to add some better target acquisition without spending a fortune. (If installing fresh you do need to still buy a detent and spring)

Adaptable usage over several product lines AR-15 Thru AR-10

by Paul Black, Verified Owner from OH, United States Written on June 2, 2026
I have used this with very good effect. It does need an occasional charge in the field. I use a small ultraviolet flashlight, and it charges sight post well. Of course, shield from your opposition is necessary. I would certainly buy again as this is a superb choice.
Pros:
  • Looks great. Easily chrged with a black light
  • Quickly charged afield
Cons:
  • The glow from sight dwindles fairly fast
Best Used for:
  • Night Time Operations.
Would recommend: Yes

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.
