SLR 15 lower matched with Magpul UBR

[JustMatt]

I just finished my lower build in anticipation of getting my upper finished soon. I went with a SLR15 lower, Ergo grip Tactical DLX and a MagPul UBR. I put it all together with a Stag LPK. First time using a UBR and although I haven't shot it yet it is looking to be a fantastic addition to my new AR.

Looks good! I think you will be very happy with the UBR.

I have one of those lowers too. I am very impressed with it.

Rob, did you fiddle with the trigger set screw at all? I didn't mess with mine at all but I was curious if it could cause my safety selector to be a bit tight.

Mine is stripped right now. I dumped some parts in it to see if they would fit and then pulled them out again.

I built a S&W lower with DPMS lpk and it went together like butter. I used a RRA lpk in this lower and it felt a little grittier going together and the safety selector feels realy tight.

To use the trigger uptake/creep adjustment screw is rather simple. Cock the hammer. Add some type of medium strength thread locker to the screw, I use medium (blue) loctite or nail polish will work. Tighten the set screw all the way in until the safety selector won't rotate. Now slowly back the set screw out until the safety selector moves freely, you have now set up your lower for the minimum trigger uptake/creep. If you desire more trigger uptake/creep, then back out the screw until you find the setting that you like.
