These look nice and fit the Thril mags, but they really are plus 4

by steeveebee, Verified Owner from VA, United States Written on August 21, 2026
These fit the new style Thril mags, the ones that hold 35. Not sure on the clear Lancers, I have a few but didn't try.

First, they are not +6, they are +4. I can fit 39 in and not 41. The 3 stars are really due to that discrepancy. If it said they were plus 4, it would be 4-5.

One other thing, when you attach these, you may be doing it more or less permanent. It would have been better had there been a hole in the bottom to poke the bottom follower up to take these out. Removing them may damage the spring as-is.

I may remove mine and drill a hole in the bottom, we'll see.

Fits the newer THRIL mags, have not tried on Lancers

by steeveebee, Verified Owner from VA, United States Written on August 1, 2026
I like these overall. They add +6 to the 35 round THRIL mags, the new style.
I'm not sure if they fit on the Lancer mags, and they are not advertised to.
They look great, and fit well. My only con is that they'll be hard to take off. A small hole in the bottom to poke up the floor plate would have been a good feature.
