A look inside the Larue 5.56 PredatAR.

2016-07-23 21.19.58

The Larue PredatAR has a free floating lightweight barrel in a proprietary upper with free floating hand guard.

The barrel is made in house, the barrel nut is 1 1/4 inch.  The heat treating method that Larue Tactical uses gives it a golden, almost brass like color.

The upper and rail have mating surfaces to ensure alignment.  4 screws hold the rail to the  upper, with helicoil(or similar) inserts.

So, why did I have this one apart?  I was showing it to a friend expounding on how great Larue stuff is.  When I got home, I was looking it over again and I noticed a very small amount in play  in the barrel.  After removing the hand guards I found the barrel nut was loose.

Now, even more annoying is that I don’t have a wrench in 1 1/4 inch size, I visited several local auto parts stores and hard ware stores and the half dozen stores I visited this weekend didn’t have a crowfoot wrench in that size.

Goes to show that no matter what your equipment, you need to inspect it regularly and have spare or backups.

A look at HK416 sights.

2016-07-16 11.01.58-2

HK offers fixed diopter sights for their HK416/MR556 rifles.  The rear sight drum has different sized openings set at different heights for 1, 2, 3, and 4 hundred meters.

There are two versions of the rear sight for different barrel lengths.  They are marked by dots under the 200m aperture.  The model for the 10.4 inch barrel has 1 dot, and the model for the 14.5 and 16.5 inch barrels have 2 dots under the 2.

The single dot shows that this model is for the 10.4 inch barrel.

The front sight isn’t adjustable, so the rear sight has to be adjusted for elevation and windage.  The rear sight windage adjustment is adjusted by using a screw driver on two screws.

The top screw is loosen to allow for adjustment and then the screw on the right is turned to move the sight.  1 full turn moves the impact 6 inches at 100m.  Tighten the top screw back down after adjusting to lock the sight back into place.

Inside the drum there are two tabs.  Compressing both tabs inwards allows for the drum to turn adjusting the elevation of the rear sight.  You need to turn the elevation drum in 1/4 turn increments for 1.5 inch adjustment at 100m.

If you don’t have the proper HK rear sight tool, a pair of needle nose pliers can be used.

These sights can be annoying to zero, but they are fun to use.  But if I was going to be shooting any sort of competition or precision I’d rather use A2 sights with their smaller peep aperture and simpler easier tool less adjustments.

Tactical Tailor/Mil Spec Monkey Adapt Pack

In the past my go to general use back packs have always been the Eagle AIII and the ATS/Lightfighter RAID but they were somewhat overkill for what I usually needed. With that in mind I recently started looking for something a bit smaller, lighter, and cheaper.

In my search I came across the Adapt pack produced by Tactical Tailor and available through the Milspec Monkey website. The pack is a variation of Tactical Tailor’s Fight Light Removable Operator Pack and priced at a reasonable $99.00

The Adapt features a 17” tall x 9.5” wide x 5.5” deep main pocket and a 14” tall x 8” wide x 2.5” deep side zipper front pocket for a total volume of 1178 cubic inches.

Here it is with a .50 cal ammo can placed inside to give you a rough idea of interior size.  There was a bit of room on all sides to put more stuff into the compartment.

The large main compartment has two elastic pockets built into the sides for holding things like water bottles.

The smaller front compartment is lined with Velcro for attaching Velcro backed pouches inside.

The exterior of the pack features MOLLE webbing on the front and sides, the front being four columns wide and three rows tall and the sides being three usable columns wide and three rows tall.

The front of the pack also has a Velcro portion for attaching patches, and length adjustable elastic cord for securing things like jackets.

The top of the pack has the industry standard carry handle and two Velcro closure ports for routing cables or drink hoses.

One of the main features of the Adapt pack and its Removable Operator Pack cousins is the ability to securely attach the pack to a larger ruck sack or the back of a plate carrier and quickly attach or remove the pack. To that end the Adapt comes with two MALICE clip adapters that attach to the host equipment that then clip into fastex buckles near the pack’s shoulder straps.

There are a second set of fastex buckles designed to have MOLLE webbing threaded through them mounted on the lower sides of the pack to secure the bottom of the pack to its host equipment.

When being used in this fashion the pack’s shoulder straps can stowed in an internal compartment to reduce clutter. This compartment can also be used to hold a camelbak style water bladder.

Given that I bought this pack for its compactness I haven’t had a reason to attach it to any sort of larger load carrying equipment, but have found another use for the shoulder MALICE clip adapters. I run a carabiner through the webbing on each and then use those to clip the pack to the head rest posts of my truck seat that way the pack is secured, easily accessed and up out of the floor and seat.

My only point of concern with the pack is the stitching for the MOLLE webbing on the front of the pack doesn’t seem very substantial. It’s not been an issue so far and there are no signs of the stitching pulling out yet, I just wonder if it may be an issue in the future.

So far I’ve been quite happy with the pack. It’s proved to be a useful grab and go type pack for day trips. Given that the main Loose Rounds test area is on a fairly remote mountain top I usually throw a change of clothes and misc other personal items it’s nice to have on hand in the pack. Clipped to my headrest it holds what I need and keeps it out of the way. I also used it at the recent NRA annual meeting to hold my camera, a second lens, rain jacket, etc. The pack is a nice mix of just big enough to hold what you need for an active day without being overly bulky or heavy.
