SRC-308 Modifications

One of the best (and worst) aspects of the AR platform is the ease of making modifications and the huge number of accessories out there. Being a “basic” model the SRC-308 comes from the factory with a very basic set of features. I think the guys at Windham figure that whoever buys the rifle is going to customize it so start with the absolute basics. I am no exception and I am not eve sure this particular rifle made it out to the range before I started making modifications to it.

Stock SRC-308

So, what have I changed and why?

Butt Stock

The basic milspec AR stock leaves a lot to be desired. It’s hard to get a good cheek weld, it rattles and there is no recoil absorption whatsoever. The lack of of a recoil pad is a non-issue in 5.56/.223 but on a .308 I would really like a bit of a rubber between me and the recoil.

(Odd side note: I don’t mind the heavy recoil of an ultralight .357 magnum or a .44 magnum but rifle recoil does bother me. Weird, I know)

Hogue Overmolded Stock

The one thing I did like about the included butt stock was that it had a built in sling loop.

I replaced it with the Hogue OverMolded Collapsible Buttstock. It offers a nice cheek weld, and a but of recoil padding at the rear. It doesn’t lock into place but there is an internal liner that keeps it from sliding around or rattling. It works well and was cheaper than an equivalent Magpul stock.

Hand Guard

The circular A2 style hand guard on the SRC had to go. The diameter is huge for those of us with little sausage fingers and there was no way to mount a rail or a

light or any other accessories to it.

I went with a standard Magpul MOE hand guard. I have them on several of my a couple of my other rifles and they work fine. They are not my favorite but it does what I need it to do at a reasonable cost.

Rail Section

One of the things I wanted in a hand guard was the ability to mount a light or a small section of rail. The MLok slot on the MOE and a small bit of MLok attached rail allowed just that. Now I have the option of mounting a light. I have several high powered white lights I can now mount, if need be. I have a green light for night hunting if the digital night vision doesn’t work as well as I hope or if there is a reason I can’t use it. I can also mount a second IR illuminator should I want a different wavelength of IR, a more powerful illuminator or just a second as a backup.

Muzzle Device

KVP Linear Compensator

In many cases I will be hunting with another person beside me. When shooting at a group of scattering hogs on the run it takes a lot of concentration and care to keep muzzles pointed in a safe direction. With a muzzle device that ejects hot gases upwards and/or to the side you can easily run into a situation where the gases can also pose a risk (at minimum a comfort risk). No one wants the blast of hot gases off a .308 in the face or to be deafened by the sound. So, I replaced the old birdcage with a linear compensator from Kaw Valley Precision. That way all hot gases head towards the hogs instead of towards a buddy or upwards into the line of sight of a scope that uses light in the infrared (heat) wavelengths.

Sling

The rifle came with a basic nylon sling but I went ahead and upgraded to the Magpul RLS sling. It has a little wider strap so it will not dig into my shoulder as badly. It also similar to a 1917 or Rhodesian sling in that there is a loop within the loop that can be used to help brace and stabilize the rifle while shooting from an unsupported position. This is a non-issue when hunting from a fixed position in blind or stand but a lot of our hunting is on foot, stalking through heavy brush and along trails. There is not always a convenient tree branch to help stabilize the shot and this style sling will really help accuracy in those situations.

Magazines

The SRC-308 came with a single Magpul 20 round magazine. I have picked up another of those as well as a 10 round magazine. For whatever reason 5 and 10 rounds AR-10 magazines are hard to find at a reasonable price right now. I will keep my eye out for a couple more as they are lighter and don’t stick out of the rifle as far (to catch brush and briars). We will see how it goes but I don’t foresee many times when I will need more than 5 or 10 rounds for hunting. Even with a suppressor, the hogs start to scatter pretty quickly after the first one goes down.

That’s all I have changed so far and all I plan to change at this point.

Take care and God bless.

  1. Probably going to be abused but I’ve got views on Tacticool and tricking out guns.

    Firearms are just tools and the best are often the least tricked out.
    Probably the most well known is the AK47.
    10.5 pounds of REME (Rough Engineering Made Easy) that works every time.

    I’m also minded of what a mentor once said as I drolled over a 1980’s Steyr.
    “Very nice but can you drop it?”. I didn’t but got the lesson he was teaching.
    Basic is good but plastic and tricks are for clowns.

  2. I think a sling is important to be able to carry a rifle efficiently. I use it like a Rhodesian sling so it also helps stabilize the rifle when there is not a tree or rock to stabilize it on.

    I replaced two pieces of plastic with two better pieces of plastic. I might replace the front grip with a metal one and free float the barrel at some point but that will have to wait a bit and really wouldn’t add much for the purpose I have for this rifle.

    We hunt a lot at night so a bit of rail to mount a light on is a good thing and doesn’t make the rifle any more or less durable. With a Digital Night Vision optic I can mount the Illuminator there.

    I replaced one metal flash hider with a different one that will help keep the muzzle blast from affecting those beside me.

    Lots of debate between whether the AK is as reliable as they say or the AR is and fragile. From what I have seen both are very reliable when properly maintained. Personally, I like and own both. For hunting I prefer the .308 and the modularity of the AR. For the end of the world as we know it? I would prefer and AK but for compatibility with the rest of my family and most of the rest of the country it will be an AR-15 in 5.56. It is equipped with an optic, light, and backup sights.

    What am I missing? What did I do wrong? If anything.

    God bless and take care.

  3. Nothing, and incidentally I used to swear by my old Garard sling.
    I suppose I still regard long guns as only a tool and thanks to a very patient mentor, there isn’t a lot I can’t get a fair tune out of. Never excellent, just competent.

    Tricked out works for some yet I’m old school and know from experience the more you bolt on and change, it ends up doing two things:-

    It can change the point of balance which can have ‘unexpected’ effects on recoil disturbing your all important cheek weld to more important things like how a magazine feeds or the effective operation of the ejector.

    Then there is how a rifle “rings”.
    The harmonic vibration of a barrel changes and therefore your POI can move or your accuracy open up with a change of sling or the fitting of a different flash eliminator, stock, or front furniture.
    Change the barrel and you could end up with a completely different beast in your hands.

    Which doesn’t matter I suppose if you have the one weapon but own two of the same model and only one has been tuned?
    I’ve seen it before when changing weapons in a hurry. The weapon feels different and you have to retrain yourself to cope aka get back on target. Only sometimes it’s when that matters a lot.

    Anyway that’s my tuppence (2 cents) worth of knowledge spent.
    Enjoy your new steel and God bless.

    1. As always thanks for the insights and knowledge. I appreciate it.

      It also reminded me of some of the other reasons I changed a couple of the thing I did but forgot to include. The new stock has a recoil pad that helps tame recoil and get back on target more quickly. It is also a bit heavier. This means it is a bit more sturdy. It also helps to shift the center of gravity away from the muzzle (it was a bit nose heavy for my taste). The handguard is a touch lighter and narrower which shaves a bit more weight off the front en and helps me get a better grip on the front of the rifle.

      If I go with a free floated barrel and new handguard it would definitely change the barrel harmonics. Swapping the plastic snapped between the existing attachment points shouldn’t change the accuracy enough to notice with the ranges that I typically hunt (30-200 yards). Plus the rifle is already more accurate than I am ;-0

      Take care and God bless.
