Some thoughts:
-The magazine it comes with is really heavy. Using my ghetto scale, a D&H Mag weighs in about 5.5 oz, a Pmag 6 oz, the T97 mag at about 7 oz (it really feels like a brick).
-I honestly don't mind the magazine release and I understand why it is the way it is (edit) - watching this guy, he seems to have his load and unload down to a science:
-Speaking of mags - the .50 MAGS THAT SHALL NOT BE MENTIONED absolutely DO NOT fit. If you use one, you'll need to disassemble the rifle, wedge a screwdriver in the mag, use a C-clamp to hold the mag release, and hit the screwdriver with a hammer in order to get it out.
-Magpul Gen2 Pmags are out. D&H, LAR, Nork CQA Mystery mags, and Tapco Pmags are in (Tapco's dont drop free)
-Read the instructions and make darn sure you hold the butt stock with your right hand when you disassemble - the return spring is under tension and flies out with a LOT of force, so don't put your face behind the buttstock when you're taking it apart.
-The cleaning kit is indeed absolutely adorable...
-2 Ar-spec risers mounted on a barrel clamped pic-rail appear to give a TRS-25 a near perfect cowitness with the iron sights (I'll fine tune it tomorrow at the range).
