Interesting spot for an accessory rail!

 

 I've always thought that , still wonder what their intended use for it was . I plan on putting my Video Camera on it to video shooting this rifle .

I gotta say one thing...your work area is the way it should be...well kept and clean! :) Wash

 

  Thanks , but its not always like that , I sometimes have ten things going on on that bench at the same time & it gets cluttered real fast . <thumbsup>

  Got a bunch of stuff from Brownells yesterday , one thing that is interesting is the Strike Industries Dust cover , I like it & will probably never buy another MilSpec std Dust cover . I like how it has 308 imprinted or molded on the cover also . I got it in black , they have other colors & different configurations . I just got the std one , but it was easy to install & can easily be removed if needed , but I don't think I have ever removed one after it was initially been installed .  

 

 I'l post some photo's here after I down load them.

Those things are pretty good, especially for how cheap they are. Sure beats buying V7 dust cover parts for a lightweight build too.

  I also installed the Magpul rifle stock & removed the JP , VTac Hand Guard from my 16'bbl. rifle & installed a Midwest  SS gen 2 to match the Uppers on both rifles , since the Tactical Machining Upper I installed on the 16" was a low pro..

Now all I need is my Criterion 18.5" bbl. & I be busting caps . <thumbsup>

 

 

 My 16" with new Midwest Hand guard , I have to shoot some to see how I like it . I'm also going to see how the QR rings work , going back to zero ,because the scope was sorta in the way .

Nice. I almost just ordered a standard dust cover for the new build. Maybe I'll try one of those. Have some eBay credit I need to waste before the end of the month.

Just got the Strike Industries dust cover in FDE, and get this...used my ebay credit to buy it!

A little flimsy and the fit isn't the best, needs some off around the top edge and the bottom hinge portion rubs until it is about half closed, I think the spring tension moves it around some. Can't say I'd recommend it but maybe it will break in.

I emailed SI and then went to check ebay but the item was removed from my purchase list with a note to contact ebay if I have problems and the seller doesn't carry it any longer.....makes me think it may have been a knock off <dontknow> . The packaging looks the same ......knew I should have ordered from Primary Arms instead.......

Could be the "capsule pattern" makes it feel weaker, maybe just some fitting will do it, I tend to be a bit anal about these things..........

Does that Strike Industries dust cover have an adjustment on the detent under the spring? I recall seeing that feature 

on a AR15 poly dust cover (Don't remember the brand) awhile back.

Mine fits perfectly, better than the standard steel ones on my baby AR's, though I got the smooth black one like SS.  I will say it beats having to remove the barrel nut to take off/install the dust cover, and it seems like it's holding up pretty well so far.   For $14.50 from Primary Arms, I cant complain:

That is the exact - exact - same detent that Matrix Aerospace is putting into their lower receivers, to tension the upper receiver when it's closed.  Slick as $hit setup.  <thumbsup>

The patent pendingUDC (Ultimate Dust Cover) is the easiest to install, best sealing , lightest and quietest port door cover available! The SI AR-UDC-E is the first quick disconnect ejection port cover featuring an internal lip which provides a better seal against the elements (True Seal Technology). It is constructed out of a high density polymer material making it more durable and functional than the traditional dust covers. The uniqueinternal detent rod design enables users to attach and detach the cover in 5 to 10 seconds with ease. Features an adjustable detent set screw in order to compensate wear on the receiver and increase or decrease opening power.There are multiple designs to choose from to customize your AR!

 

 

 

 98 , didn't you have a guy that had a Upper that the catch for the DC was worn & wouldn't hold ?  I see this feature is not on the std AR15 version , but they have an enhanced one that does & the 308 ones all have it .

Yep, and the guy was too cheap to buy this 5.56 version and try it out.  I was gonna buy it just to try it, but told him I'd cut his stock ejection port rod to take his non-fitting one off, rather than take apart his upper.  I told him I'd give him the new cover if it works. 

 

He didn't want to do it...   <dontknow>

 

 

 

 

 

EDIT - Matrix sticks that little gem right in the back of the FCG pocket, where the lug on the upper will contact it - easy tensioning device, and pretty damn smart.  <thumbsup>

I havnt messed with it yet...seemed pretty well set as it came. You just stick a flat tip in there and turn it up/down as needed?

Yep, insert flat blade screwdriver enough to compress the ball, and it contacts the slots.  You're raising or lowering the whole device to make the adjustment, not really changing the tension of it.

 I guess I will have to take some measurements to see what size would be appropriate for the Lower receiver . What size is in that Matrix ?

 

  Now the biggest question , does it make a difference & I don't mean does it just mean it tightens up the Receivers . It would have to help the function , accuracy or service life of the rifle . Otherwise its just gimmick. <dontknow>
