THE GOOD: What AR accessory has impressed you the most?

[SonOfAGunn]

Ergo Tactical DLX Grip
Surefire Brake (will be trying out the Warcomp CTN)

[Achilles11B]

This southpaw is a big fan of the Magpul BAD Lever. The Aimpoint PRO and Magpul magazines also impress me, they're not fancy but they do the job extremely well.

[The-Hammer]

Pretty much anything Geissele, especially their SSA-E trigger and MK8 rails. I'm also a big fan of the B5 Enhanced SOPMOD stocks.

[ExplorinInTheWoods]

Trijicon optics, magpul mags and bad lever, vtac slings, surefire muzzle devices both war comp and socom brake, geissele/alg and cmc triggers.

Most surprising thing? Magpul padded sling. I've have VTAC, VCAS, and everything in between. Magpul padded w/ QD's is the best I've used to date by a wide margin.

Aimpoint H1/2, the standard of sighting equipment for a modern rifle.
Magpul PMAGs. Price, quality, reliability, why buy anything else? They are inexpensive and deals can be had, stack them high and stack them deep.
My Kahles K16i. The capabilities packed into one 16" rifle this optic provides (if you start with an accurate rifle to begin with) is quite amazing.

From a guy who has owned Larue, LWRCI, Noveske, KAC, and BCM....A BCM upper and lower combo w/ an H2 on it is a hell of a lot of rifle for not a lot of whole lot of money.

I think the most important part of any weapons system is how it fits in your hand (more so for pistols but definitely applies to rifles). Replacing the stock pistol grip for a more HK like grip was the biggest improvement I've ever noticed. I like both the BCM gunfighter grip (on my spikes) and the new magpul MOE K2 (or K2+) on my DD.

The fact that they upgraded the electronics to use a 2032 battery instead of a 1/3N while also doubling the battery life, i might just need to pick another one up.
