    Crosshair Prescision was in the works with one but haven't heard from them in quite a while. Did you hear of any timeline on the PTG? The Tromix looks to be nice. I will likely order me 1 in the near future.

    The only down side to the Tromix mag well is that polymer mags need a good smack to lock in right. Now that may just be my particular rife and others may have a different experience. Just something to keep in mind if you want to use Magpul, Hexmag, or similar polymer magazines. Since I have all steel and aluminum magazines now, it's not an issue for me.

    My magpul mags do require an extra push/smack to lock into place. When I release the mag, I usually rock it just a little to get it to let go. I use the magpul 20 rnd mags and have no feed issues with my rifle. MVP 5.56/223 with Tromix mag well.

    I think the tolerances on mine are tighter. I have to smack a mag pretty darn hard to get it to lock, even with the bolt open. I'm glad yours works better.

    I did a little work on mine but it should not have significantly changed the stop to locking ridge dimension. My write up - - Modifications/My MVP 223 Mods.
    I agree that they are tight with polymer mags. I bought the Tromix trigger guard as well. I just like metal on my rifles.

    I looked at those but liked the offering Crosshair Precision had better. Personal taste. Tromix does makes some nice stuff.

    I use Tromix mag well on my Mossberg MVP Predator 5.56 with poly mags Magpul PMAG 10 gen.M3 with no problems. Magazine locks in easy and reliable. Maybe I'm just lucky?

    I'm not sure. While some have bought Tromix stuff, CHP was more active on this site than Tromix was. I think that was a big reason there is more CHP items owned by members here.

    In any case, we would need to wait for more replies from those who have bought Tromix in order to see if you were lucky or not.

    Anyway, I like it much better than the original plastic one. Magazine sits tighter and no feeding issues whatsoever.

    Are they that tight with the p and hex mags? I have a healthy investment in both but if there are issues I don't want to order it. I have the trigger guard both CH and Tromix

    I had an apparent brain fart on which mag well I have. The Tomix mag well in my rifle is very tight with P and hexmags. One other seemed to be tight but ok.

    I just traded all my P and Hexmags for steel magazines to solve the problem.

    Pmags:

    My Tromix mag well is snug but I used my rotary air tool with a craytex end, and emery cloth to clean up the tight spots on it. Use some spray on dykem or similar, insert a pmag and wiggle it a little. Take out the pmag and look at the rub marks. That will tell you where and how you can clean up your mag well.

    Regarding Tromix mag wells. Mine, (and I assume all) was made from two cast/machined halves fastened together. It is a good production method to build a mag well.
    However, on MY rifle, the pillars, action, and stock dimensions were off and when I installed the new mag well and torqued the action screws, the mag well halves spread apart slightly.
    After some careful calculation, machining on the pillars and stock, and some JB weld, all is well and works good. I did not include this in my write up on Modifications/My MVP 223 written back earlier this year. In my opinion, my rifle was out of spec from the factory and I state so in that post. Just be aware stuff like this can and does happen. When it does, it's time put the thinking cap on and use dial calipers to measure parts. BTW, my rifle turned into a nice working rifle. I am very pleased.

    Finally, I met Tony (Tromix) personally as I live about 45 minutes from his shop. He seems like a good guy and I like his products. In no way can I fault his product and I highly recommend it. When you start changing things on a rifle, not all things are just a drop-in product. I hope this helps some folks with after market mag well issues. My two cents. Jim
