Question: I have a Sig Sauer AR15 with magpul furniture, will it fit in the vices?
Document: I just purchased the Caldwell Lead Sled DFT on Amazon. I wanted to use it to sight in an AR 10 style rifle with a PMAG 20 LR 7.62x51/ .308 20 rd. magazine. The problem is that these .308 Magpul magazines will not fit between the 'dual frame' rails! They are too close together and there's no way to adjust them further apart. Why would they design this product to only work with 223/556 magazines?
This is a very well built product. It is adjustable to fit most guns that I own from the small gauge to the large.
In other words, this isn't a set-it-and-forget-it rest. I still need to practice a good grip, good breathing, and good trigger pull if I want to keep my crosshairs on zero. Having said that, the sled reduces my effort at holding zero by 70%--so much so that I was tempted to ignore breathing discipline while shooting.Cons:- It's difficult to fit more than 3Caldwell Lead Sled Weight Bagson the tray.
It is, frankly, effortless now.Pros:- Despite the many pieces in the shipping box, it's easy to assemble with included tools and great instructions. Total assembly time was about 25 minutes.- Made of substantial materials:  beefy metals and very sturdy components. It weighs about 20 pounds alone. It doesn't feel cheap and I was pleasantly surprised by its robustness.- Fit and finish is terrific:  Good paint, good texture, close tolerances. The green cordura fabric will last a lifetime.
The 2 25 lb. bags of shot will fit into the 2 Caldwell Lead Shot Carrier bags, but the filled bags will not fit under the 'dual frame' rails when placed on the trays.
The wobble has been taken out of the front rest and the split rails allow for a pistol grip or long magazine to fit. This allows a greater number of rifles to be used. The adjustments are much easier than the original. Multiple individuals have used it on the range. They all seem to agree that it is much improved over the original.
It made me think, "Wow, it's definitely worth what I paid for it."
Easy to use. Makes the difference I needed to sight in my hard to handle high powered rifles.
I have been using cheaper versions of this product for years. After finally getting the real thing. I will never use anything else.
I love this thing. I have used it, so far to site in a couple rifles and it is dead on. Very easy to use, very fine adjustments, VERY well built.
