You will need 2 t-7 torx mini wrenches not included - POF USA Drop In Trigger Assembly 00858P

I received my trigger a couple days ago but had work I had to do before I could play with it. Last night I had the time to install it and it was easy to install (I am a new guy to AR's only been playing with them for a few years). I had a problem that stopped me in my tracks. The final step is you have to use 2 T-7 Torx Mini wrenches at one time (One on each side) and without them everything just hung loose and there was a danger of loosing the top pin. I had to use a nylon wire tie to secure it so I would not loose the parts and this morning make the 20+ mile drive to Home Depot and was lucky to find a couple of sets of them. I have a few of those that have came with scope rings and brass catchers. Its sad that 30$ scope rings and 30$ brass catchers have what you need included but not 159$ drop in triggers.

The package does not tell you thats its needed either. If you are a gun expert I am sure you have it but if you are a newer guy this review is a heads up so you can be getting what you need while waiting for the trigger to arrive. I have 2 tool sets I purchased from Brownells with 50$ bits for gun work and it was not in their either, there were some but not small enough to fit.

I did put 10 rounds down range with it today and its much different to what I am used to but I think I like it, if it works out for me I will be buying a few more for my other 4 AR's I have.
