Adding to my collection of "Sniper rifles in cases", I bought an INTOYZ PSG-1 (2000, ~$15 shipped) Been debating getting one for a while. First thoughts when I received the item was the sheer size of the carded item.
Out of the Box
INTOYZ has a lot of nice little details on their model. First, is the safety selector lever.
This model is pretty good. However, I have one complaint about the case. There's no ideal way to store the extra bullets in the case, as provided.
The main reason I picked up the PSG-1 was for my Yamato Solid Snake. I was pleased to find that the grip slid into his stiff hands with relative ease. Snake's hands are absurdly stiff and difficult to get some rifle grips in there. The PSG-1 slid in like Snake's hands were designed for it.
I was pleased with the construction and general build quality. There are only four PSG-1 models I'm aware of on the market in 1:6 scale. One being from Hot Toys' Resident Evil line, the second being the Yamato version from the Sniper Wolf doll, and the other being ZACCA's World Weapon Collection. Hot Toys' PSG-1 is perhaps the easiest to obtain loose, with ZACCA being the rarest. However, in terms of overall detail, the INTOYZ model may be the best if you like all the little mechanical details. Molding quality and paint, I would probably guess Hot Toys' has a leg up in little molding details. However, I didn't see the right side safety indicator markings on some product images of their PSG-1.
If you don't care about the case and just want the rifle, you're better off getting a loose Hot Toys' rifle. The bipod may be too fidgety and the remaining details may be too delicate for rough play. It's a lot cheaper if you're on a budget to get a loose rifle.
On a side note, INTOYZ also makes a MSG-90 which can be bought for approximately the same price as the PSG-1. As far as I know, no one else makes a MSG-90 model in 1:6 scale.
