All of the MDT products I've owned have been top quality. The only issue I ever encountered was with the first TAC-21 for a Savage. Tried to put a 10 TR into it, and the bottom bolt release caused a fitment issue. A quick call to MDT, 5 minutes with the dremel and some touch up paint and I was good to go. I should also state that all of their products have produced an increase in the accuracy of the firearms that were mounted in them.
The TAC-21's have always been a favorite of mine, as you can see from the list. However, they are a little bulky, and do add weight to the gun. I really like them for target shooting, but don't know if I would want to try carrying one all day in the bush, on a hunt.
Picked up the LSS-XL for a Reminton 700 in 7mm RM. It did everything it was advertised to do. They are lightweight. Increase accuracy. Just a great chassis. Only one problem - I just hate the way the LSS and the LSS-XL look. The XL is better than the LSS, but I still could't warm up to the look of it. Can't bring myself to look at the Savage Stealth series either. I know it sounds petty, but I just couldn't "fall in love" with a rifle that I considered that ugly. Rifle went into a B & C Medalist, and has since been sold off. Which reminds me. I've still got the LSS-XL - need to put that on the EE.
The HS-3 was put on a .223 Savage with a custom barrel from Jerry at Mystic Precision. It shot like a dream in that chassis, and coyotes learned to fear that rifle. It was a really nice chassis, and kept the weight realistic for a field rifle. I liked the HS-3 and would still have it, but the wife's nephew's second cousin twice removed was out at the house and fell in love with the stock. So it went to him for his target/coyote gun.
Now the .223 is riding in another TAC-21, just because I found a killer deal on it in the EE. Still a little bulky and heavy, but it will do for now, until I get it into the chassis that I want it in. Please see below.
The ESS. Again saw this chassis on the EE. Wasn't a killer price, but it wasn't bad, so I picked it up. I had one of the Remington AAC-SD's with a 16.5" barrel in a Magpul Hunter stock. They're a decent stock, and it let me use AI mags. The rifle went into the ESS chassis, and it was like a dream. The ESS, as far as I'm concerned, is close to the perfect offering from MDT. It's not as bulky as the TAC-21, has even better ergonomics, comes with an MDT stock, and doesn't add a lot of weight. The only thing I'm missing on this one is a folding stock capability. Unfortunately I'm a Savage guy - don't know why - so the Remington is up in the EE right now. Once it's sold, I'll be buying another ESS chassis from MDT. Maybe 2, as I'd like to do another custom barrel from Jerry, but in .308 this time.
Personally I love the MDT products. They have always given me huge value for the price point. The only real negative I have is with the TAC-21 weight/bulk of it, yet I keep coming back to it, time and time again, because of the advantages it gives me at a price that I can't argue with. Think about it for a minute: If you have a rifle you really like and want to get rid of the cheap plastic stocks that all manufacturers use today. Order from Boyds and you're $350, never mind an HS Precision, or MacMillan. Then bottom metal so that you can use AI mags, which are so convenient and they're everywhere, and you're another $350 at least. Then there's still inletting, bedding, etc. MDT gives you all the performance advantages, at less than the custom stock process will cost. NOW that they have acquired the rights to the JAE products, I can't wait. Not sure if there will be another ESS in my future, or an MDT/JAE offering.
