I fitted the SH-4 Gen II 4-16x50 to a Remington 700 using the Arken Halo # AHSR-34Low, CNC machined 7075-T6 aluminum, 34mm, split type scope rings. They feature a single 0.195” wide recoil lug integral to the lower ring base that fit the Pic rail slots perfectly having only 0.005" clearance in the rail slot. These Low height rings elevate the scope centerline to 0.920” above the Picatinny rail. Using these Low height rings produced the most compact bolt action rifle setup I've ever put together. I love how low the scope centerline is. My eye naturally drops into the scopes pupil eye box after shouldering the rifle. These are very low rings! It was a tight fit making sure everything missed each other but it all worked out in the end. Care must be taken when mounting to a bolt action rifle to ensure there is proper clearance at all points. A slight clearance relief was required (minor filing) on one Picatinny rail ‘dog ear’ corner to avoid contacting the scopes erector spring plug located in the lower turret body. The bottom of the turret body cleared the top of the Picatinny rail by only 0.015". I initially mount the rings on the Pic rail and check the alignment with a piece of perfectly straight machined bar stock that I have just for this purpose. I did not feel the need to lap the rings as the scope was a great fit into the saddles after using my scope bar. No slop at all when the scope is placed into the lower ring halves. The close fitting recoil lugs on the lower ring bases help to avoid miss-aligning the rings on the Pic rail. While I prefer a single 1/2" nut clamping fastener design, at the ring clamp to Pic rail interface, this two screw design works fine if your very careful not to misalign the clamping plate due to uneven gaps as the two screws are made up. Go slow and make sure the plate meets the rail flat and aligns straight to the underside of the rail. The clamping plate is aluminum and could twist and deform if the plate doesn't meet the rail evenly. If that happens the rings may not be in alignment and could damage the scope tube. That's why I pre-fit the rings using my scope bar. A single one nut design greatly reduces ring miss-alignment potential and is much quicker to install. That said............these rings will work fine if you pay attention. These rings have only a very small gap between the ring halves after being installed. I'm not sure why Arken feels the need to cut this clearance so close. This is not a show piece rig where every parting line is scrutinized for looks. You can't see a gap at first glance.....but it is there. Only a 0.004” gap was remaining on both sides after the specified 18 in./lbs. of torque was applied. On hard use field rifles.......I generally like to see more clearance than that between the rings to ensure the halves don't touch and for ease of installation......... but as long as they don't touch they will work. Four thousandths doesn't leave much room for error though. Understand that 18 in./lbs. isn't a lot of clamping force for such a heavy scope. If you have a heavy recoiling, light rifle with a heavy scope like this one and if they don't clamp the tube well........... the scope could slip. This heavy Remington Sendero in .25-06 doesn't kick at all............so this rig should not see any scope movement. If I was mounting this scope and rings on a lighter and larger caliber rifle.......... I would have cut the ring gaps larger just as insurance for my piece of mind. Due to the small ring gap.....go slow when making up the ring half screws to ensure they pull down evenly. I used feeler gauges to check ring gap clearance as I drew them down to final torque spec.. I used a TPS Products #20200-001-01 XP extended length, one piece steel, matte black, Picatinny 'Dog Ear' style scope mounting rail. The front end of the extended length rail just missed the taper of the objective bell by about 0.060" and the rear end missed the magnification ring by about the same amount. It was close but it worked. I'm not real happy with the powdery black coating Arken is using on the scope and the rings. It's not very durable. The slightest contact with any thing metallic will mark or scratch it. I need to put some matte black paint in the Torx ring screw sockets as they now look terrible even though I used a very tight fitting Torx bit to make them up. Even with my above comments............I really like this scope. Looking forward to see what comes next from Arken.

Fact of physics. A larger tube DOES NOT give you a better (larger) field of view or brighter image. Only the shape, diameter and quality of the lens and coatings can change that. The large tube diameters common in ELR scopes is ONLY to allow a great deal of elevation and windage correction in the turrets. The larger the tube diameter is.........the more internal room the erector tube can move up and down, which is required to allow large elevation adjustments in the turret. The actual diameter of the focused light image passing through the erector of a riflescope is quite small. Much smaller than the internal tube diameter of even a 1" scope. Arken is concentrating on the ELR sector because that's what's driving the market right now but I also have discussed the need/want for SFP hunting scopes with them. They said they will be coming at some point in the future and I'm very happy about that because I think they offer a great product for the money. I'd like a 100 yard Fixed Parallax, Second Focal Plane, Four Power Zoom, 4-16x50mm, 30mm tube, low height, non-adjustable turrets with a simple BDC type reticle to use for bullet drop. I don't need adjustable turrets for tremendous distances when hunting. I personally WILL NOT take a shot on un-wounded game past 500 yards and neither should the average hunter because they rarely (if they ever have) practiced target shooting beyond that distance. Responsible hunters have a duty to put their game down quickly with one shot. Hunting at extreme distances allows to many uncontrolled variables into the equation (for the average typical hunter) that can and very often result in lost game that eventually just dies. I've seen it happen more than I care to admit by friends and other hunters I just met. I have personally taken an elk at 652 yards with one shot but I will not do that again. At the time I was very active at 1000 yard shooting and could reliably put a round in the boiler room of a large game animal on a cold bore first shot. Even if someone is an adequate marksman, there too many other factors that the hunter cannot control that can and will affect the outcome. I will not shoot that distance on any animal again and I wish others would consider their ability BEFORE do so. Leave the ELR scopes on precision target rifles and blast steel and paper instead of animals at those distances. Enough of my hunting ethics. Arken seems to be offering great scopes for the money from what I've seen, read and personally witnessed at their shop and by reviewing my SH4 Gen II 4-16x50. There will ALWAYS be manufacturing problems and some samples will have problems from time to time. 'HOW' Arken responds to and handles those defective samples will contribute to determining their future. From what I've personally seen and heard, those young businessmen are doing a great job and have the right attitude toward product quality and customer service. Bringing a new product to market like a riflescope line is no small task but they are on the right track. They are concentrating on the ELR sector right now because that's what's driving the market at the moment but I'm looking forward to their versions of hunting scopes and binos in the future. I'm wishing the best for these guys.
