How so?I vote Timney. A little fiddly getting the set screws tightened down against the receiver though.
Timney's AR trigger (the gold anodized one; I have 3 of them) has a total of 4 set screws. There are 2 that tension down against the bottom of the receiver to take up all the gap underneath, and then 2 more go on top of those locking it in. The one issue is that the two set screws that lock the bottom two need to be taken out, and the hammer springs go right over the top of them. You sort of need to fiddle with them to get them around the spring leg and back into the threads, being careful not to cross-thread them.How so?
I have the Geissele and Larue. Both are great but I favor the Larue.I tend to stick to Geissele or Larue. The Geissele SSA-E has a 3.5lb trigger. It's very nice, but MSRP on it is $240. This time of year though you should be able to find it on sale.
The Larue MBT-2S is also a very nice 2 stage trigger. It's $89. I would definitely look into that one.
I have installed a few of the RRA match 2 stage triggers in rifles. I like them a lot. They are fairly economic and better than the basic 1 stage military style. I have the varmint model awaiting a dedicated lower for a 6.5 Grendel upper I have. I think I mocked it up but didn’t get to really use it yet. But it seemed to be performing as advertised. The parts come with a different disconnector spring. RRA will say it comes with a certain color instruction card but I asked what was different? They said It was the spring that made the difference. But the cards have the same text. I think the card is to identify the right kit from a bin for sorting.We all know the expensive and excellent reputation of Geissele. I've heard great things about the Larue line up too.
Larue also has an excellent single stage trigger. Larue doesn't carry a large pin version unlike Geissele.
There are also great triggers from KAC.
@brianns I've heard about Rock River's triggers but, I don't know anyone with one to voucher for their quality. Do you have one?
