Don't cheap out on accessories....and follow the manufacturer's torque specs!

I’ve invested in inexpensive parts in the past and I’ve even used airsoft accessories on real fire arms thinking I would save money.  In the end, those parts failed and I ended up buying the real deal anyways.  From my personal experience, I recommend staying away from cheap airsoft scopes and red dot sights.  I’ve also had bad luck with scope rings and bipods meant for airsoft (fake Atlas bipods) so I’ve learned to stay away from those as well.




Recently, I’ve learned to always follow the manufacturer’s recommended torque specs.  I found out the hard way with a set of Primary Arms scope rings I bought recently and over-torqued the keeper screw nut and ended up stripping the keeper screw.  I’m sure this could have easily happened with a set of more expensive Leupold or Nightforce rings, but then again, I might have paid more attention to the torque specs if I paid more money for the rings, lol!



These are a set of Weaver Tactical 6 screw scope rings that I’d purchased a long time ago for a scope that I’d long since sold.  I’m not sure if it was the new owner that may have over-torqued it, but after a few rounds of .308 through the rifle it was mounted to, the nut came off the scope rings.  It looks like the keeper screw snapped and you can still see a bit of it inside the nut.


This is a Champion pivot bipod.  It’s basically the same as Blackhawk or Caldwell in that they’re all clones of the Harris, except these are probably all made in China.  Not a horrible bipod if you don’t abuse it, but the mounting screw stripped on me and this bipod failed me after a few years of use.  I’ll probably replace these with Harris bipods eventually.



The Vortex bubble level wasn’t cheap at the time, but I guess the older ones were inexpensively manufactured in China.  This level was on a scope I bought several years ago, and the bubble has gotten bigger over the years.

SWFA SS 10x42mm Mil-Quad Reticle and Primary Arms 30mm low rings

My 700P’s been without glass for a while but as I have a few other precision rigs, the 700P wasn’t a huge priority.  I wanted to keep my 700P as plain as possible, and though I didn’t need a huge magnification range for long distance, I wanted to get something that I was used to, something will a mil reticle and mil adjustments. 

My buddy Alex recommended I try the SWFA SS 10x42mm with the Mil-Quad reticle.  Apart from my Elcan C79 3.4x, I’d never had a fixed power scope and I wasn’t sure I’d be comfortable with using one.  But I’d heard good things about it so I decided to give it a try.

The scope was sold by Primary Arms, the same company that sells scopes of the same brand. 

http://93zj.blogspot.ca/2017/08/pa-scope.html 

The entry level Primary Arms scopes are just that, entry level.  Made in China, mushy controls and a very ugly overall appearance.  They might even be clones of the made in China Falcon line of scopes.  It is however first focal plane and the glass is of decent quality.  The reticle is crisp and fine, with a bullet drop built in.



Anyway, the “Super Sniper” 10x42mm has a bit of history, originally designed and sold by Tasco, apparently built for military applications, though I've seen very few pictures of these on military rifles "in the wild".  I found this image, but I'm not even sure it's legit:



Apparently the QC on these went downhill for a few years, along with Tasco’s other offerings, until it was sort of resurrected by SWFA who purchased the super sniper distribution rights and got QC back up to a decent standard.



The scope came in a plain cardboard box, nothing fancy (not expecting much for $299 USD), with the scope wrapped in bubble wrap.  





The scope appears to be decent quality.  According to Primary Arms, these are manufactured in Japan, though I could not find a manufacture stamp anywhere on the scope.  The finish is a matt black and it appears robust enough.  


The turrets aren’t bad.  The clicks are audible and positive, and the knobs are of a decent size and marked clearly.  After you find your zero, you unscrew the three set screws, lift the cap off and drop it back down to zero and tighten up the set screws again.  


The focus ring is where the magnification ring would normally be.  There is a side focus model for an extra $100, but I just got this one.  






I also ordered a set of Primary Arms 30mm low rings, which appear to be the same design as Millet, Vortex and Burris tactical rings.





The rings are of decent quality for what you pay for.  I would say these are better than the weaver tactical rings.  










Anyway, being in the land of perpetual rain and overcast skies, I didn’t get a chance to get some quality pics of the glass, but there’s a shot of the reticle at least.  I’ll update this when I figure out how to take a decent picture of the glass and see if I can capture the clarity I can see with my eyes.

As far as the scope being fixed a fixed 10x, it wasn’t all that hard to get used to.  It was very pointable, and finding the object/target was fairly quick.  The focus ring was also easy to use and I’m looking forward to trying this scope out when the weather gets better.

Primary Arms 4-14x44mm, FFP, ACSS HUD DMR reticle

I've had my ACR for a while now and I've never had proper optics for it.  I tried to test it for groups once, but I only had a 2moa red dot with a 3x magnifier.  A few weeks ago, I took my ACR out with the Leupold from my Mk12, but since it was only temporary, I had no motivation to dial in and actually test for groups.  

Well, one of my pals Mark runs one of these on his XCR topped with a Primary Arms 4-14x44mm, same ACSS reticle, and I was able to make hits out to 550m with little effort.  I didn't even have to dial, just held over using the reticle and had no problems.



The scope was moderately packaged, nothing fancy and it came with the bikini lens cover which seemed like decent quality, instruction booklet, sticker, lens cloth and an allen key.  I flipped through the instruction manual and though the scope is made in China, the instructions were well written, easy to understand and had no spelling mistakes or grammatical errors, lol!



Overall, the scope appears to be of good quality.  Primary Arms is an American company and this particular model is manufactured in China.  They have other models made in Japan, but I've heard that the QC for the Chinese made models is still fairly decent.

With anything made in China, I always have concerns about QC.  Manufacturing in China has gotten better over the years.  I used Millett scopes for years and never had any issues with those.  The finish on this one seems like it was done right, no rough edges or spurs in the metalwork like with my Noricno firearms or airsoft/Deal Extreme scopes.  Plus the thing had some heft.




The turrets are mushy, and it's easy to lose track of how much you've dialed without looking.  My buddy Jay told me it doesn't track very well either, but I can't say mine will be the same.  For the price, I wouldn't expect it to track as well as my Steiner, Bushnells, or Vortex Razor HD2.  In fact, since it has the bullet drop reticle built in, I may not have to dial at all on my ACR.



The reticle itself is clear and crisp, a lot finer than on my Leupold VX-3 Patrol, and it appears like it will be more useful than  the simple TMR reticle on the Leupold.  The glass is pretty clear for the price, but the photo really doesn't do it justice.  The weather's been crappy in the lower mainland with smoky haze from the forest fires so it doesn't make for good pictures or testing glass clarity.

In terms of eye relief, there's a few inches of it, so I don't think I will be getting pirate eye, even if I mounted it on something with heavier recoil than my ACR.  Before I mounted it, I had some concerns that the eye box wasn't great, but once I had it on the rifle, it seemed better.  I won't know for sure until I have this thing outside and I'm actually looking downrange behind my rifle.  


I've had about half a dozen of these American Defense one piece mounts for my other rifles.  I wanted something with quick detach in case I ever want to swap out the PA from my ACR and throw a red dot on, or just run the iron sights.  I've also always been a fan of the unimount type designs and have had a good experience with ADM, so I got one for the PA.


The ADM came with a small instruction booklet, a sticker, some thread locker and an allen key.  The torqe spec says the ring screws are rated for 20-25in/lbs.



According to ADM, their mounts have been tested for 50bmg and have held zero.  I think that will be plenty for my ACR.  I have one small gripe about the design in that the rings are secured with horizontal screws, rather than traditional screws that drop in from the top down.

I'm sure there's a reason for this design as ADM is not the only company who've adopted this design, but I'm not sure what that reason is.  The reason it's a gripe is because gravity isn't there to help retain the screws when mounting your scope.  It's not a huge deal, and as mentioned before, I'm quite happy buying more of these mounts.

Anyway, I can finally test the ACR for groups with this setup.  I've had a positive experience in the past with this model, so hopefully there's some consistency in the line and this one works on my ACR as well as it did on my buddy's XCR.
