Building Out Geissele 10.3
Written on Dec 17, 2025
I purchased this to complete a Geissele Superduty 10.3 upper. I have used the Geissele springs and heavy buffers in all my shorty uppers, as well as the lighter buffers with the springs in 16, 18, and 20 inch rifles. Excellent product of the price.
Mounted Trijicon RMR HD
Written on Feb 01, 2025
Used this mount on the 3.5x, battery powered, ACOG to mount a Trijicon RMR HD. Mounted perfect. Easy as 2 screws. Mounted very solid and seems to be initially aimed/zeroed with the cross hair of the ACOG prior to confirming zero. Works awesome. Thanks.

Review for
EOTech G-Series G33 3x Magnifier
Purchased as a Christmas gift for my adult son to go on his AR build, Geissele 11.5 URG upper with folder, light, RC2 suppressor, and Holosun HS510C. Even thought the G33 is intended to mate with the Eotech Circle of Death optics, the G33 works great with the Holosum The reticle does magnify but is still usable and very clear. The G33 works great with its flip to side mount and the quick release mount works flawlessly. We will use the G33 with the Holosun while testing against an Eotech ES series at some local gun dealers to see if he may want to upgrade and go the fulll Eotech system.
I was always not a fan of the magnifier and usually prefer straight red dots, or an ACOG, however I intend to purchase a G33 for myself to use on the same Holosun sight, equipped on a Daniel Defense 7 inch 300 Black Out upper.
