TTAG Tests New Frontier Armory Polymer Lower

The Truth About Guns has posted a review of the New Frontier Armory LW-15 polymer lower/butt-stock for AR style rifles. TTAG notes:

The LW-15 is basically all plastic. The buffer parts, bolt catch, action springs and pistol grip screw are metal, but everything else is made of polymer. Even the mag catch, trigger, hammer, safety and takedown pins are made of some tough, hard plastic.
The body of the receiver is made from an extremely rigid glass-filled plastic. The design is externally similar (read: almost identical) to the Plum Crazy polymer lowers we’ve seen for a few years, but New Frontier uses a different polymer formula and different reinforcing fibers. If you like to watch gun porn of the ‘snuff’ variety, New Frontier has some brutal testing videos on its website.
Somewhat surprisingly, the review is overall very positive:
Regardless of its unorthodox construction, the LW-15 operates exactly like any other AR lower. The all-plastic single-stage trigger is an unexpectedly pleasant surprise: it’s kind of hard to describe a trigger pull scientifically ... but the LW-15′s trigger pull is very smooth, not too heavy (5.2 pounds) and fairly short with minimal overtravel.
It’s also a little mushy/spongy/vague (take your pick) but it’s one of the best triggers I’ve seen included with a lower-priced AR. I wish it were lighter by a pound or so, but it still helped deliver some amazing accuracy.
The selector lever has a smooth and positive feel, and it would only be better if it were ambidextrous. I like that the LW-15 is ready-made for an ambi lever: it has ‘SAFE/FIRE’ markings on both sides of the receiver.
When it came to magazines, the LW-15 was like Mr. Creosote: it ate everything we put on the table. (No ‘wafer-thin mints’ here.) My Magpul P-Mags, Joe’s steel magazines from H&K, and Wayne’s GI magazines all snapped home neatly, fed perfectly and dropped free when released.
