HSP WML Weapon Light

I've had the HSP WML for about a month now and have been running in on a couple long guns.  Here's what I've found so far...

Pros:
-Cost.  The light can be had for around $120 shipped.
-Uses one 3V CR2 lithium battery.
-Easy on/off mounting.  Very secure once mounted
-It handles recoil well.  No issues on the 12ga pump shotguns
-Momentary on/off only.  I generally prefer simple on/off controls on defensive lights but this may be a "con" for some folks.
-200 lumen output
-Has two methods of preventing it from accidently being activated (1. twist the bezel or put up the hinge on the back of the light to prevent it from being hit by gear/ect...)
-Lightweight.  3oz with battery (includes mount)
-1.5 hour constant run time.
-Cost.  Comes in at around $109

Cons:
-Only comes in black (due to it being the strongest polymer)



Here's a video showing some day/night shooting, a comparison with a 104 lumen LED Maglite and a Surefire X300U, a deomonstration of the mounting system, and a discussion of the pros and cons of the light:

AK-47 (AKM) Muzzle Device Flash Test

I took a few AK muzzle devices out to the range at night to see how much muzzle flash each would produce with Golden Tiger 124gr FMJ ammo.   The muzzle devices were:

-Krebs Custom Birdcage
-Damage Industries Brake
-CNC Warrior 4 Piece
-Yankee Hill Phantom
-Tapco Slot Device
-K-Var "AK 74" Brake

Top two at reducing muzzle flash were the CNC Warrior and Yankee Hill Phantom.   The Krebs Birdcage wasn't too far behind....

Here's the video showing the results so you can see for yourself:

MWG IK-520 Bulgarian 40 Round AR Magazine

It seems the panic for AR mags is slowly dying down but a mag that's relatively new to the US market (I think I got mine at the end of 2011, maybe early 2012) is availible pretty consistently from a couple websites (Midway, mwgco.com, and others....).  Here's what I've found so far...

Pros:

-Reliable.  I've never had a malfunction using these mags.
-Available.  They're in stock and ready to ship.
-Designed Ivan Kolev (designed the SLR 106 mags for those that care about that kind of thing)
-Steel reinforced feed lips.  Lots of folks prefer this over the all polymer competitors. Me, I don't have a preference either way as both Lancer and PMags have been extremely reliable for me over the years and one uses metal, one doesn't...
-The ribbing gives a good positive grip on the mag when inserting it.
-They weigh 6 oz
-No issues with inserting when fully loaded and they drop free.

Cons:

-They're not going to fit in a lot of mag pouches.
-They call their follower a "stable, level follower" but I'd rather see an anti-tilt design personally.  Again, they've always been reliable but non anti-tilt followers just make me think of old school USGI mags... and not in a good way.
-Cost.  They're $25 which may not be too bad these days but deals can still be found on 30 rounders so the cost may be prohibitive for some.

Here's a video review where I do a little shooting, break down the magazine, compare it to a D&H mag (with Magpul follower), and discuss the pros and cons of the mags:

Battlecomp 1.0 Review

I finally broke down and dished out the cash for the Battlecomp 1.0 & I've been using it on a couple ARs for a few month now and here's what I've found:

Pros:
-Very good muzzle control during rapid fire strings.
-Minimal flash signature (see video for the night shooting).  Similar to A2; perhaps slighly more but not much.
-Minimal side blast. 
-Machined stainless steel with a black oxide finish.   It's holding up quite well.
-Crush washer included (it just annoys me when they're not...)
-Carbon doesn't seem to build up in any one spot on it so it requires minimal cleaning.

Cons:
-Cost.  It sells for around $120 +/- $15

Here's a video with some day and night shooting, a discussion of specs and my overall thoughts on the brake:
