Wow, had Geissele packs prior to this

Review by Martin W. on 11 Apr 2025 review stating Wow, had Geissele packs prior to this
After buying a Springfield Waypoint 2020 that comes with a triggertech included. I thought I’d try the triggertech on my newest AR build. It’s phenomenal. And at 4. 5 lbs it feels like much less because all of the slop and take up is eliminated.

Great trigger, very much recommended.

Fast shipping from Rainier. The price was right. (On Sale) And the gun shoots amazing right out the box.

Very Nice Picatinny Mount Stock

Review by Louis R. on 11 Apr 2025 review stating Very Nice Picatinny Mount Stock
I mounted this on a UIC stock with an integral picatinny rail in the rear. It mounted easily, and appears in all facets to be well made and the usual Haga designed excellence. The only reason I gave it a 4 star rating is I would prefer one other bolt or fastener in addition to the picatinny screw to ensure the stock doesn't come loose.
