The rail is provided with 3.8x0.78 inches, measured it 20,65mm wide and 5.3mm profile height, a total of 7.8mm high and 98mm long.
It is not a "lead track" soft heavy lead, but of hard lightweight aluminum. Robust, can not bend with your bare hand. I guess it was originally called "Lead Rail" was probably rather "guide rail" translated "lead track" and "attraction" rather than "sight" ("Sight") ... But the purchase worthwhile.
The grooves are even labeled "B1", "B3", "B5" and "B7" what one knows rather from the professional field.
Unfortunately, in most stores, almost exclusively sold scrap especially when "eGun" which has so far almost always bent and is often begrochen, although the rails there are twice as expensive, and (allegedly) from USA ... That is why I very pleased that this track is so high here, probably even withstand strong back trust, since it makes a high quality impression. So I'll probably get even more ... Definitely not to be compared with the "eGun" Scrap-.
The shipment took exactly 2 weeks (14 days), which I think is very good!
So what remains to be said? "Made in China" is often underestimated. Meanwhile, China is often much higher quality and better than what you get elsewhere. Just try it. An ACOG replica I had ever fetched for decoration "Made in China" for 45 Euro and but that was even more robust, heavier, more accurate and better than that of Walther (the point was too big for me) or even better to scrap eGun "Tacworld" for 90 Euro, which fell apart even after the first shot ...
