I have a UBR and mostly like it. I am not a huge fan of the screw-in on the end, it always seems I have to over-tighten mine to make it all stay snugged up. Otherwise, great stock, not light, but very solid.

Just go to a Fastenal. You can pick up a handful of set screws for pennies. Another place you can find small set screws is any hobby store that sells RC models (Planes, cars, boats, helicopters, drones, etc.). 4-40 is a common size for that hobby. However, technically you don't need the set screw. The end plate keeps the spring and detent contained just fine once you tighten the castle nut, and most ARs don't have a set screw.

They use a set screw there? Why? So you can remove the grip without the spring and detent coming out? Do you plan to remove the grip often? Every AR I've ever played with didn't have a set screw there; only a counterbore on the top of the grip and the grip itself contained the spring and detent.

What's the advantage of having set screws? So you can adjust spring tension? So you can remove the buffer tube and/or grip without the spring flying out? I've never used set screws for the takedown pin or safety selector and have never had any issues with function. I've never wanted more spring tension than what you get from the conventional spring length and containment method. Most AR lowers don't have set screws.

I am speaking for the rear takedown pin. Thats what seekins has and my mega as well. I have never seen one on the safety detent either. That would require cutting the spring very very short

Ted thought you meant for the Safety selector because of how that post was worded. Lol I believe what SVT meant was, "They don't include the 4-40 set screw for the takedown spring nor do they include the detent for the safety selector." |

You're correct, CF. That's exactly how I interpreted his post. I was thinking that was really weird, as it would then require a much shorter selector spring, and couldn't figure out what the benefit to that would be to justify having to use a non-standard length spring.
I can sort of see the benefit to having a set screw behind the takedown pin spring, though I'm not in the habit of ever removing the buffer tube once installed, and the end plate contains the spring just fine.

yeah bad wording - the rear take down pin is the one that is tapped for the set screw and is located under the grip beside the safety selector hole. not on the rear of the receiver like most.

I use just a touch of Loctite on that screw and have never had it move in use. It was a pain to remove and reinstall on this receiver though. |

Ah, I see. If it's not located on the rear of the lower receiver where it's contained by the end plate, it would then REQUIRE a set screw.

yeah its directy beside the safety selector hole under the grip. I've had other receivers that are on the rear with a set screw as well. I like the set screw

Got all my parts in but an adjustable gas block...... how I missed that I don't know. Used a standard but with the suppressor she blows back grim everywhere. ST did you get the 4-40 set screws? |
