Questions & Answers
Will this fit on the Kentri 3.5 buffer tube. Manufacturer Answer

We have not physically tested this, but it appears that the UMS would work. The UMS's cavity for the buffer tube is 1.75". Keep in mind that the UMS utilizes screws to attach to the buffer tube, so it will leave marks on the tube where installed.

No place for quick disconnect sling attachment? Manufacturer Answer

The UMS is not designed to include a QD sling attachment location. We recommend using an End Plate that accepts the QD swivels.

Unique minimalist! by Judson, Verified Owner, May 4, 2023
I'm not one to adjust my stock, I like it fixed so the Phase 5 Weapon Mini Stock works perfectly for me. If you don't need padding and a soft butt it's good. It looks nice not cheap and comfortable to shoot

Great for a Range Rifle by Nopers, January 15, 2022
Works just fine on a standard buffer tube, however, I did switch out to the hex buffer tube for a more complete appearance. The fit and finish is great, and comfort is as good as could be expected. Would recommend for a range gun.
