Howdy, you fine rifle people!
I have a S&W M&P15T, and I just installed a new grip, a CAA G-27. I know, I know, CAA doens’t make very high quality stuff, but, I like the way it feels, and I got it for nearly nothing.
Now, here’s the deal. When I installed it, I removed the stock A2 grip, then when I installed the G-27, I put a dab of blue loc-tite on the grip screw’s threads, and installed the selector spring as it should be installed.
Now, when I move my selector, it takes a lot more force to move it from S to F, than it used to. Anyone know why this is? Is the little hole for the selector spring shorter than the standard grips? Making the spring tighter? Has anyone else experienced this? Is there any way to loosen it back up a bit? It’s not really a problem, it’s not too hard to manipulate, it’s just annoying, since I’m used to it being so smooth :). Thanx for any replies!
Here’s my rifle (old pic, I have since added a LaRue bipod adapter and Harris BRM.

Did you remove the detent at all? If not, it would be my guess that there is a difference in the depth of the hole. FWIW- I have a CAA G27 grip on my AR and I like it just fine. It’s the same one that used to be on my M16A4.
I’m thinking the detent pin is binding or possibly the spring.
Try removing the grip and making sure everything is lining up properly.
Is it binding on the grip itself? I had that happen with a Hogue grip and had to whittle a bit of it off.
I bet the spring is either missing, bent or not in the hole.
The hole in the grip is probably a bit more shallow than the original grip.I had this exact same problem with a Hogue grip on my old Armalite.
My fix was to just clip a coil or two off the selector spring.I had considered just drilling the hole in the grip slightly deeper but figured replacing a spring was much cheaper if I made a mistake.
Anyway it worked like a charm.
I also like to use a glob of TW25B on the selector detent to help keep it smooth and to hold it in place when I remove the grip and or selector.That helps keep me from dropping it in the carpet while Im fumbling around.
HTH
He stated that he installed the spring. Also, if the spring was missing there would be almost no resistance as the detent would drop down.
I also have this grip and when I installed my new Timney trigger it was rough especially when putting it back on safe. I lubed the whole thing and gave it a few flicks. It was better. Then when I went to the range it got a workout enough to say that I don’t have a problem anymore.
Very true, missed it, my bad.
Thanx for all the replies. I thought about removing the grip and double-checking it - but I used Loc-tite on the grip screw, and didn’t want to break it loose again unless I needed to. I’ll go at it again, and smear some TW25B in it (I just got my first syringe of the stuff last week, I love it!) and maybe snip off .01" of the spring or so, thanx for that idea Blankwaffe!! Thanx for all the other info too, everyone! I’ll post back with results.
My 700 Fils here.
I would take the grip off (hopefully you used blue Loc-Tite) and make sure that something isn’t FUBAR. There may well be a problem that was overlooked. You can place the sspring in the original grip and with a Mk1 MOD0 eye ball see if there is a big difference in the protrusion of the spring.
If you clean the screw and the hole putting new Loc-Tite on the screw and tightening it back down shouldn’t be an issue.
I had the same issue a while ago when changing grips. The selector would move, but it definately required more force.
So I did like 'gunz recommends and eye-balled the spring protrusion from both grips. The replacement grip’s hole was visibly shallower. So I stuck a tooth-pick into the original grip’s spring hole and marked it with a pencil at the junction of the top of the hole. I then stuck the marked toothpick into the hole on the replacement grip to see about how much material needed to be removed.
I then rummaged through my various tool-boxes and found a drill-bit that was very close to the size of the hole, and on low speed with light pressure I drilled out the hole using only brief increases in pressure and frequently checking the depth.
When the hole was at the same depth, I stopped. Problem solved.
Mission accomplished. I just snipped a coil off the selector spring, and viola’ - now it’s a lot easier to move, like it used to be with the A2 grip.
Thanx for all the help, everyone! I was a bit upset over this new grip, and now I am enjoying it as much as I wanted to when I ordered it
