ALG Trigger kit with a Seekins lower question

[abilliott]

Started putting together a build last night and I got my ALG ACT out of the package and noticed a shorter, noticeably larger diameter pin that was included. There is
nothing in the instructions about this pin that I can find. Anyone have any clue what it is for? Here is a link to Brownell's that has a photo of the parts for reference.

Also I noticed that my Seekins lower has some allen screws at the grip area that are for adjusting the "trigger reset"? I'm no gun smith but what benefit would I gain by
adjusting this? Any words of wisdom or advise on adjusting this safely?


Thanks for the help fellas

That pin is probably a slave pin which you put in the trigger to hold the parts together when installing. Then you push the actual pins through and push that pin out the side. Just makes it easier so the holes are lined up.

Can you take a picture of the allen screw you speak of? I have not noticed anything like it in my Seekins lower.

Its under the grip, where the take down detent and spring go. There is a threaded hole with 2 small allen screws. you can see it from inside your lower behind the trigger. It will be at an angle. Its as if it applies pressure at the trigger unit and angles it slightly? Did that make any sense? I don't have mine with me right now for a photo but i'll see if i can't dig one up on the net right quick.

BTW thanks for the slave pin info! That makes sense, however i've never had a problem getting those pins in! Now the pin that holds my gas tube in my gas block last night almost sent me to drinkin ;-)

I will be pulling mine apart to put a new trigger in on Monday so I will look for the allens but I didn't remember seeing them there.

Yeah the triggers aren't hard and the pins will slide in but I think the makers just want to make life easier for us sometimes LOL

The Seekins lowers have a trigger reset adjustment screw (that won't likely be needed with your ALG trigger as they are FAR better than your average GI trigger in terms of how short the reset is). You can use it if you find that you need to shorten or otherwise adjust your trigger reset/overtravel or if you don't need it, you can remove the screws altogether. I don't have a good pic of my own from my Seekins builds, but here is a link that will show you some good pics:

Thanks for the link. I hadn't noticed the screws. Had a Geissele in there and putting an AR Gold in so don't think they will be needed but for a GI package I can see where they might be of help. That Glen thinks of everything LOL

I finally got a Seekins lower to go with my upper and rail and up until I installed my lower parts I didn't realize he had built that option into his lowers either. I knew about the captured spring screws and not needing roll pins because he threaded holes and includes set screw pins etc. I have a Timney in mine, I still set the trigger screws per the included instructions. Just got it together and I have t shot it yet. Like Rob said, with a factory mil spec trigger it would make a big difference and has been a trick to improve those for a while. Just didn't know he included that into his lowers until recently.

I like the hell out out all of my Seekins parts, Glen does make great stuff. The lower and his rings are by far my favorite out there

I didn't have my Geissele in hand yet for my last lower build so I threw an extra parts-kit trigger I had laying around in the lower just to test it out (DPMS or RRA...can't recall which). The trigger reset adjustment screw is a DEFINITE plus for any basic, parts-kit type trigger. While the weight of pull still sucked royally and the overall pull was rough as hell...the trigger was noticeably improved for follow-through purposes. I have yet to need the adjustment screw with any Geissele trigger I've run in my lowers though (and with ALG being a part of Geissele, I can't imagine it'll be needed there either...same for the AR Gold triggers).

Just looked at this! Wow i need to check mine when I get home because I didn't even notice the allen screw that holds the take down pin in mine. I wonder if it was just
missing? Anyways I was quite upset when I realized my "MIAD" wouldn't work because the spring falls out because there isn't a surface on the miad that holds it in. I put
my "A2" grip on it :-( until i found something to correct this.

Them Seekins pics have me fired up. Man them are beautiful. My 3 gun upper is finally on its way from Joe Bobs, still waiting on the 15" rail that i ordered through Seekins. I'll have to check out my billet lower for the trigger reset screw. If you dont plan on using it (I will be running a Geissele also) should you remove the screw or just blue loctite it out of the way? Also do the forged lowers have the same adjustment screw?

One of my SP223 lowers arrived from the transferring dealer without the cap screw for the takedown pin detent/spring hole. I got with Glen and he sent me a "few" replacements as my local Fastenal didn't have what I needed in stock at the time after he provided me with the dimensions of the screws.

I can't recall the specific size of the hex head cap screws needed, but I'm sure that someone may know off the top of their heads (if not...Glen will if you want to check locally before having Seekins mail you what you need).
