Benjamin My Modified Akela .22

Just thought I'd show what I did with my Akela.

Bit of background ... I have a ranch in central Virginia with the typical mix of poultry (chickens, turkeys, guineas, ducks, geese, etc). So in my barn I have bags of feed for them. The nice sheltered conditions in the barn and the feed together ... brings rats. Even if you put the feed in metal cans, you still get rats using it as a place to live, where they like chewing wires on the equipment and other things. They have to be dealt with, and a hot, fast shooting PCP rifle like the Akela is just the tool.

So I bought an Akela .22 PCP to deal with them. If I went with a firearm like a .22LR pistol/rifle, I'd be punching holes in the barn walls and roof, which is not good. With the .22 pellet, it's fast and lethal, but the half the grain weight of a .22LR means no wall/roof thru-n-thru shots. But oh wow do they stop a rat!!

Using the Akela I found the crisscross of wood behind the pistol grip to be in the way. Silly, but often when grabbing to raise it while keeping my eye on a moving rat, I was often grabbing the crisscross and not the pistol grip. The wood crisscross is not needed structurally, and without it if you sling the rifle muzzle down, your shoulder now fits nicely into that open spot since they put the sling mount right in front of it. I found it cleaner and easier to use without it.

Oh and after removing the crisscross and now sanding, I also sanded down the sharp edges in the stock, giving it a more rounded look. Not for everybody, but again it's the fit I liked. I was going to re-stain it, but once you get into this wood, you find this Turkish walnut is NOT north american walnut. It's nice for what its mounted on, but it's nothing to protect and display. So I went all-black. Just my pref...

I tried various optics, but the fast shooting on moving rats in the low-lite barn was better suited for a HALO sight. Big field of view and you can engage with both eyes open. I went with the Holosun 510C HALO (about $300US) and it's great. It has the "motion-detection on/off" feature, so you're not manually turning it on and off. I run it with only the center "finite" red dot, not the dot and circle as most guys do when running a HALO on an AR. The finite dot makes precision rat head shots easy.

In my barn I sit at one end in the evening. That's when the rats get active. I sit behind some boxes with a two very low wattage spot lights (about 15W each) in front of me pointed away at different angles. It gives some light inside the barn and makes it hard for them to see me behind them. I found that anything brighter spooked the rats and fewer would come out. I turn down the brightness on the HALO's red dot to compensate for the low-light conditions and let my eyes adjust, then start watching the rafters. The rats are a challenge! They hardly EVER stop and give me a nice stationary shot. When on the rafters, they stay on the move. To include regular hops to other rafters.

A key thing with this Akela rifle that you have to keep in mind though, is the height of your optic. On a normal hunting rifle the optic's rectical is about 1.5" above the bore. The Akela with it's raised rail and then height of the HALO sight itself, the height of the rectical over the bore is over 2.5". So when making barn-range shots (10-50 feet), the convergence of the bore's line with the visual red dot sight line is intense, and actually opposite what you may be used to if you're a normal outdoor rifle shooter where on distance shots you're compensating for bullet drop. Here, at these ranges there is no appreciable bullet (pellet) drop to worry about, but that convergence of 2.5" bore and sight lines are a dramatic factor. Especially when you want to put the pellet into a 1/2" rat-head kill zone anywhere in the 10-50' barn-rat range!!

I first sighted it at 50', the length of the barn, but found I had to hold the red dot a full 2" below the rat if they were running a rafter only 10-15' away. Wow, that's a lot when it's a moving target and you want to put the pellet in that 1/2" rat-head kill zone.

So what I found for barn-rat shooting using this setup was to sight the HALO in at 25', then if I have a rat in closer (say 10-15'), I hold the red dot 1" high, since the bore line hasn't come up yet to converge/cross the sight line yet. If you don't, it's a full miss on that small rat-head kill zone.

Out past 25', I have to hold under. That's right ... "under". Not "over" as if you're out shooting a rifle at distance and compensating for bullet drop. Here you're still compensating for that high optic's visual line covergence with the bore line. And it's intense for such a high sight and such a small 1/2" rat kill zone. At 40-45' out, I'm holding a full 1" under the rat.

Anyways, hate to bore you folks with all that, but before I went into rat killing here at the ranch, I was a normal rifle distance shooter and always thinking "hold over" if past your sight in range, due to bullet drop. But here I had to ignore all those decades of training and do the opposite ... hold "under" when in the barn and shooting past my sight in 25' point. It's just different. And my sighting at 25' and then holding the 1' over or under before and past it, I found it much simpler than sighting it in at a longer range and then dealing with what could be over 2" hold over before the sight in point. It just hurt my head less.... Since I never use this outside with normal long rifle shots, sighting at 25' was perfect (for me).

Anyways, this rifle shoots fast, flat, and accurate. I can't say that enough. With these mods and the HALO sight using it's single "finite" center dot, it's an awesome barn/rat rifle. And that's with the rats crossing the rafters at a hussle, with their unpredictable "quarter second" stops/pauses, and with their frequent hops from one rafter to the next. It's a challenge. This rifle is great for it. (Fun as heck too!)

Are there others that have modified their Akela? If so, I'd love to see what you did.

Very nice mods on your Akela and wonderful shooting on all those big barn rats! I shoot fruit/roof rats in my back yard and use a 15 watt red flood light in tandem with a red LED flashlight on my Prod to illuminate them (they're under bellies glow orange from the red lighting), they seem to be less wary of a red LED compared to a normal white LED. You must have a blast shooting that many each time out!

You are right ... a red lense works great on predators. We use em on our coyote rifles after dusk. The red lense doesn't spook them like pure white light does, but still lights up their eyes. We were thinking of what type of red cover we could put on these simple hardware store spot lights, but then saw that keeping the bulbs in them down to 15w it wasn't spooking them. And as a side benefit, by sitting behind the two lights, they clearly hide us. They don't catch our movement as we raise our rifles.

*Just to make it clear, when I was talking about using simple hardware store spot lights with 15w bulbs and it not spooking "them", I was back to talking about rats inside the barn ... not still talking coyotes. Would help if I had my morning coffee when I answer. <GRIN>

Ver nice, what kind of range do you get with that ?
Hi Glenn, I don't know max range, since I got it specifically to use in the barn where I don't want a firearm punching holes in the wall and roof. They say the 18grain pellets are moving out about 1000 FPS, which also helps since it's not yet supersonic ... so no crack breaking the sound barrier. Sure it's still got a sharp noise as it launches the pellet and the compressed air escapes behind it, but nothing like I'd get if using a .22 firearm in there (both noise and damage). With the quieter pellet shot, another rat will usually come out in a few minutes and not act spooked at all. But range? I'm shooting the length of a 50' long barn and the shots can be from 10' to 50'. So that's all I can speak to. I'm using the Benamin hunting pellets and they just about turn a rat inside out. The bullpup design of this rifle makes it compact and compresses most of it's weight in it's back 1/3rd. Again, makes it compact and fast. Only issue is getting the hold over/under right, which I already droned on about in the original post. It's tough telling my old brain to hold UNDER for the long shots, vice over.... But as I said, inside the barn with a max shot of 50', it's all about what the convergence of the optic sight line and bore line is at each distance ... not about bullet/pellet drop.
 
Yupp ... go for optimal sight in range ... is what I did. But still have to work a hold over & under since I'm dealing with a 1/2" kill zone on the rats, or I can have a clean miss over or under their head.

I found my optimal sight in distance was 25' since the barn is 50' long. That split the distance. I do make shot on rats crossing the roof trusses just 10' in front of me, so the hold over dope there is 1" over. Then dead on as I said for 25', but out for the longer 40-50' shots I have to hold a full 1" under ... or again I would miss the rat's head entirely. Would be much easier if the optic didn't sit so high. That's the issue. That creates a pretty radical convergence.

Hey I saw you mention putting on a regulator. Was that on an Akela?
 
Both are nice rifles. This is what I was hoping for ... to see what other guys have done to make them better fit their need. Nice wrap Mike. What do you two use your PCP rifles for?

For me my Akela is my first PCP. I live in the country as I said, and till now I dealt with varmints and predators with some appropriate firearm (depending on range of shots, etc.). With all my free-range poultry, I have a steady stream of foxes and coyotes coming to make a free meal of my birds. It was the need for something less than a firearm, but still accurate and deadly that got me into the PCP for the barn rats. And I have to admit, it's fun as hell. I almost worry now about running out of rats!
 
Glenn in simple terms for a newbie, what would adding a regulator to my rifle do for me? Does it function like a regulator on a shop air compressor, making it deliver a set amount of PSI air regardless of how full the tank is ... thus "normalizing" the air driving the shots??
Yes that's what a regulator does. My regulated fx pcp gets no more than a 15 fps spread.
 
15 FPS spread, that's better than many firearm cartridges shoot. I'll have to chrony my Akela and see what it's doing. I did find there are vids on youtube on adding a regulator to this rifle. Hate to spend even more money on what for me really is a "rat rifle". But then, tweaking and chasing ever tighter groups in anything is half the fun. I'll look at those vids tomorrow.
