The SLx optics are the heart of our lineup. The trusted optics that have built our reputation through the years. Although many SLx optics will be familiar to Primary Arms fans, we are always pushing forward with new generations and adding even more options in response to the demands of our loyal customers.

The Primary Arms 4-14x44mm illuminated rifle scope was our first step into first focal plane (FFP) optics and remains one of the most cost-effective options on the market. Having a reticle stay 'true' through the entire magnification range opens a world of possibility for hunters, marksman, and competitors everywhere. Add in "built like a tank" construction and a 3-year warranty, and it's easy to see why this scope is so popular.

  • ACSS HUD DMR .308 Reticle offers a host of great features in a clean intuitive design tuned for .308 Winchester
  • Compatible with some .223 Remington loads
  • First Focal Plane reticle stays true at all magnifications
  • 6-illumination settings powered by a common CR2032 battery
  • High strength aircraft grade aluminum body
  • Side-adjustable parallax and fast focus eye piece for crisp view of the target and reticle
  • 30mm main tube compatible with your favorite rings and mounts
  • Tactile and audible 1/10 MIL windage and elevation adjustments
  • Exposed tactical style turrets with Zero Reset
  • Shockproof, waterproof, and fog resistant
  • Parallax adjusts from 15 yards to infinity!
  • Excellent glass clarity

At the heart of the 4-14x44mm rifle scope is our advanced first focal plane ACSS HUD DMR .308 reticle. Tuned specifically for popular .308 Winchester loads, the ACSS HUD DMR .308 reticle offers a remarkable number of advanced features in a clean and intuitive design. Leads for moving targets out to a full 600 yards, wind leads, ranging, and bullet drop out to 1,000 yards, and even a MIL-ranging system are built in to the clean design. An illuminated horseshoe and center chevron allow for remarkably fast engagement of close-in targets. At any range, hits are intuitive without any need for math or digging through data books! Simply range, hold, and break the shot!

A scope that won’t hold up to real world use won’t do any good, so we built our 4-14x44mm FFP tactical rifle scope to last with a heavy-duty aircraft grade 6063 aluminum body and 30mm main tube. Waterproof, shockproof, and fog resistant, this scope is perfectly at home on an AR-15 or your favorite hunting rifle. Even better, the MIL/MIL turrets track correctly through their full 17.5 MIL adjustment range, allowing for confident adjustments for shooters who prefer to count their clicks. With clear glass, heavy duty construction, and a true first focal plane reticle that can be leveraged at every magnification, the 4-14x44mm rifle scope from Primary Arms offers shooters a versatile and effective rifle scope, covered by our 3 year warranty!

While the ACSS HUD DMR .308 reticle is compatible with some .223 Rem and 5.56 NATO loadings, we recommend the dedicated ACSS-HUD-DMR-5.56 model for guns chambered in these calibers.

My thoughts


I am pleased with my new scope. The quality of the product is excellent in every respect. I like that it has several ways of determining range and that the range holdovers are easy to see and use; the windage holdovers are an added plus. I mounted this scope on my Savage Model 10 Precision Carbine. My application is exclusively sniper rifle use, so with that in mind I would of prefered a small free-floating cross-dot aiming point over the chevron/horse shoe style, which IMO is more of a CQB style.

Nice Scope


It was easy to mount on my M&P 10. I look forward to sighting it in in the next few weeks. Very well made!



Mounted on RedX 6.5 Grendel Upper...easy zero with 27gr Benchmark and Hornady 123gr A-Max...very pleased with product.

Will be buying another one soon


This scope is very clear (even on 14 power) and the rectacle is awesome with the ffp for ranging targets. Don't think you can beat this for the price. Time will tell how it holds up. The only complaint i have which is very small is you can go to amazon and order the same scope which goes thru Primary Arms and get free shipping. I almost give this review 4 stars for that reason, but after mounting, shooting and the price i still give it 5 stars.

4-14 acss


4-14 acss, clear field of view. Super buy for the $. Sits on my 18" spr reticle coincides with Hornady 75gr super performance

Solid Scope!


A friend of mine turned me on to PA and showed me the 4-14x44 w/ ACSS HUD DMR .308/.223, he had high marks for it and said for the money you can't beat it. I took him at his word and I am so glad I did. I am a believer. Great, easy to use and understand reticle - and overall the scope is built very well. The quality you are getting at this price point is hard to beat IMO.

great quality


awesome experience as always from primary

You will not believe the quality.


Build quality is the first thing that hits you, I have tried quite a few scopes in and above this price range and this one easily beats all of them. Nothing on this scope feels cheap, if you picked it up and nobody told you the price most people with experience would guess at least 800-1000$.The reticle is something else, the word Id use to describe is "elegant", it does not feel cluttered and scales nicely as you zoom in. The illumination is crisp and doesnt have any glare or wash. The turrets are well beyond the price range, they have a clean "click" and dont have much slop between clicks. The glass is clear and bright, the metal is clean and nicely finished. I was trying to think of how I would improve this scope and to be honest I got nothing, the people who designed it know exactly what a proper combat scope should be and they made it, this scope has all the features you want but somehow keeps it at the price you want. Outstanding, well above what anyone else is making.

Excellent Scope for the Price


Built a precision AR rig, and this scope was the best in its class at this price. Close range work is possible with the illuminated horseshoe and practice using BAC or occluded eye technique.Glass is clear, knobs have distinct clicks. The ACSS HUD is what makes this thing awesome. Works great for 223 or 308. I mounted it on a BoBro QD mount and can switch back and forth between the 308 or my 223 rifle. However, double check the BDC drop with your own DOPE for slight variances with a couple loads. The manual will tell you the exact MOA drop for the BDC. Or just dial it in and use the mil dots. Overall, excellent scope for an excellent price.

4x14x44 FFP Scope


Can't wait to sight it in. Fast shipping

Incredible clarity and quality. Very impressed!


Crystal clear glass and super sturdy construction. I put this on my SPR build and have been incredibly happy. The reviews aren't lying to you! This scope can really compete with top of the line optics.Update: May 11th 2015: I finally got around to taking this out and my first shot at 100 yards was 2 inches up and 2 inches left. The adjustments are super crisp. With two clicks in each direction, I was punching touching holes. I am incredibly impressed with this scope and have no doubt of a long lifespan of accurate shooting.

Primary Arms Just Set The Bar


Crystal clear glass, all you could ask for functions and symbology, easy to use after a little patience, trial and error (as with all scopes). Illuminated (6 settings), ergonomic sturdy turrents with audible clicks finish the form. At this price, super quality and function, Primary Arms has set the bar for the competition regardless of price range in my opinion, especially for us folks who can't afford nor need big budget scopes.For those interested on my setup, I mounted this scope on my M1A with BASSETT Picatinny Rail Scope Mount Package (HIGH, so can use iron sights), the best US Army trial proven M1A Scope Mount made, period (Weaver Rings 30mm #49120), I don't believe anyone can any longer say the M1A wasn't made to be "scoped", for this scoped turned this beast into a monster !Extremely happy and highly recommend, especially if you're looking for your first scope.

Good Choice


Delivery was on time and product was delivered in perfect condition. Utilize scope on a Remington 783 in .308. Mounted clean and easily. 7 rounds of Hornady 168 grain to zero at 100 yards. Scope maintained great clarity at 500 yards and the calibrated reticle was exact for multiple targets between 300 and 500 yards. Fired at 60ft elevation, 67 degrees temperature, 3 mph headwind, 30% humidity, flat range lanes. Three shot group was easily covered by a dime. Fired from lead sled as well as bipod supported. Did not have the time to attempt past 500 yards yet. Highly pleased with the purchase and the performance of the scope.

savage model 10 p Scope.



This scope is awesome!


Dropped this on my custom Remington 700 and I have to say she's looking pretty sexy with this glass...Crystal clear glass... Buddy of mine has a scoop that's triple the price of this scope and it doesn't come close to compairing. The patented reticle is VERY nice. Takes some education but then so does everything in the long range shooting world. I purchased this with the $20 sun-shield which I think is a much needed addition for this scope -- really completes the "look" while being very functional on sunny days...

4-14 FFP scope


Easy purchase with web, quick delivery, very nice scope.

4-14x44 FFP


easy to order was there a 3 days.I have the scope mounted, it looks really nice the turrets feel good.I put the scope mechanical center it was on paper one shot.used the mil dots dialed in the was right on.I haven't had the time to really check the tracking . at hundred meters did2 mill up2 mills right it right we were supposed to.I'm happy

awesome company good product


everyone i show this to thinks i paid $500+ for it. glass is clear and adjustments are very positive and accurate. the battery will go dead fast on it so make sure you have a spare but it is etched glass so you can still shoot also the battery is an odd size so you wont find it easily. i had a problem with the reticle rotating witch was an obvious defect so i told the company. they got back to me the next day with 3 emails 1. tracking for a replacement 2. return label for the broken one 3. an apology letter. this has been a great company to work with, the optic since replacement woks great and i have not had any issues using it on my Sig 716.

love my new scope


everything was just as you said it would be . mounted it on my 25-06 Ackley and love the way it works . this years prairie dog trip will be fun . the only reason I didn't rate it a 5 , well it wasn't free lol

First Order


Excellent ordering experience. I ordered a scope after contacting Primary Arms and getting their recommendations, as well as a question on a scope mount. My email was answered almost immediately. This is a great company.

Great Scope for the Money


Eye relief is a bit narrow but otherwise awesome product. Would be 5 stars if not for this minor setback.

ffp scope


Fast shipping. Looks to be quality!

Seems like a great product


Fedex lost my first shipment, which obviously wasn't PA's fault. After a few days of back-and-forth with Fedex, they over-nighted a new one with UPS. Overall fairly pleased with customer service on this one. This isn't my first purchase from PA, but it's the first one that had any problems...because of the good customer service, it definitely won't be my last buy from them. Overall quality of the scope seems high for the price. I got it mounted up last night but haven't gotten it to the range yet to test. I imagine it should perform fine. It's not an absolutely top-of-the-line scope or anything, but I was looking for an entry-level scope for a precision build and I think this will do just fine for the goals I have in mind. The reticle detail is very clear, and illumination was still strong this morning after I forgot to turn it off for about 10 hours.

Like it


For the amount of money spent this is an excellent scope. Like firm and open controls and the side focus. Seems to be well put together. Haven't tried it beyond 100 yds yet but I do like the BDC feature.

Can't beat the price


For the money you can't beat it. Bought this optic for my Springfield M1A to get my self started and dip my fingers into some long range shooting. The redical is really cool and very useful for real world combat not that paper moves and shoots back but no the less a nice conversation piece and just incase the zombies do show you will be ready. Long term I am interested to see if the optic holds up with the M1A recoil. I would say if your thinking about it do it compared to other high end glass out there your not gonna be disappointed for the money some guys spend this much on bases and rings for a high end set up.
