Yet another amazing Holosun optic.

Written on Jan 22, 2026

I don't really know what to say that hasn't been said before. Holosun makes amazing reflex optics. I prefer them to EOTech or the Sig Romeo products. Easy to calibrate, easy to install, and durable. The reticle is very clear, and this version, with the green optic, is very easy to see in any light condition. I highly recommend this optic. This is the fifth Holosun product that I've bought, not because they keep breaking, but because I love them so much.

A pocket rocket

Written on Jan 17, 2026

I picked up this Maxim Industries PDX kit after watching a review from Short Shot Tony on YouTube about the now discontinued Springfield armory PDW Saint. That Saint was made with the Maxim Industries PDX kit, and after trying to find one, I decided to build one myself. The kid comes with a fully assembled upper, ready to be attached to your own lower, and it is very easy to do so. I attached it to an AT3 lower receiver with no issues. I really like the proprietary BCG and it's innovative buffer assembly. It does take some very slight finagling to get the upper and lower mated, but it's negligible. Recoil is very manageable with the 5.5" barrel, even in a 5.56 load, thanks to the HATEBRAKE. I added some MagPul Gen 3 MBUS sights (which actually took a little coercing to convince to fit on the rail) and a Holosun 510C-GR optic, and it acquires and dispatches targets like a dream. If you have the money for a Gucci Gun, this is my recommendation.
