I think the 16" barrel is the way to go. 18" and 20" are too long and heavy to haul around if you have to. The 16" is more than capable of 1/2 to 1MOA impacts to 600 yards which is about the max effective range of 5.56x45 anyways...although I've heard many stories about hits beyond. I can tell you that even the M4 with the 14.5" barrel works well enough as reported by my colleagues in Iraq and Afghanistan. Sub-MOA impacts at 400 to 600m. A solid gun with the right training and optics will give the balance you need in a weapon system.
I do have an SPR with a 20" bull barrel. She shoots super tight groups at any distance, but damn, I hate carrying her around. My LWRC M6IC-E is my AR of choice and is just as capable, plus I can maneuver in CQB.

I believe it makes sense.
Can you define BC in this usage?
Raising boys into RealMen!!
BC = Ballistic Coefficient

Thank you. Did you mean to say that our optics are gun specific? If so, that is partly true. Its more BC specific which in some circumstances would be gun specific. In particular, each scope has a reticle for a particular BC and in most cases means that it is for a particular ammunition load and barrel length. For example, the USO-PFI-762C is designed for the following ammunition and weapon configuration:
• 7.62x51: 175gr, B.C. 0.485-0.505 @ 2440 fps, 16” barrel
• 7.62x51: 175gr, B.C. 0.485-0.505 @ 2575 fps, 20” barrel
• 7.62x51: 168gr, B.C. 0.431-0.447 @ 2405 fps, 16” barrel
• 7.62x51: 147-150gr B.C. 0.397 to 0.410 @ 2600 fps, 16” barrel
• 5.56x45: 55-75gr, B.C. 0.234 to 0.272 @ 2660-3200 fps, 16” barrel
The RR-Evolution-5.56/7.62 that Don is getting works with:
7.62NATO BC: 2430-2700 ft/s
7.62 NATO (.308WIN) 175gr Sierra Match: BC = .505 @ 2,600 ft/s
7.62 NATO (.308WIN) 168gr: BC – .462 @ 2,700 ft/s
5.56 NATO (55gr, 62gr, 75gr) and 7.62NATO (147gr, BC: .401) (up to 600 yards)
We basically designed it for the 20" AR-10 platform shooting 168 or 175gr ammunition. 5.56x45 carries the same ballistic curve as .308 out to 600 yards. That's why it works in the same scope.
When reticles are designed, we focus on the most common weapon systems being used. The military stuff is relatively simple since there are only a few calibers that we need to work with. In the civilian work on the other hand, we have a scope for .22LR, .22WSM, .17HMR, .17WSM, and then there's the H which works with 180 of the most common hunting loads. In the H, all those rounds have just about the same ballistic curve out to 600 yards. After 600 yards, they start to deviate from each other. In that scope, after 600 yards, there are series of crosses so shooters can figure out where their impacts are for 700, 800, 900, and so on and then use the crosses accordingly.
Does that make sense?

Thank you! I hope that I can contribute to the community here. I like what you guys are all about, and if I can help, I certainly will. Shooting is a passion for all of us at PFI, so we like to be involved. I think Don got an earful from me the other day...lol.

Thank you for the suggestion. There are 3 different classes of product. The USO-PFI Series is made here in the US Optics factory. US Optics makes high end optics and the series utilizes our reticles. Currently, we have a reticle in the SR8 body designed for the MK17 weapon system, but it could used with any 16" 7.62x51 system. The other is the USO-PFI-BLK which is designed for the .300BLK and 7.62x39. Both optics are intended for military use and houses the finest components.
The PFI Tactical Series is a proprietary mil-spec product line made at the Light Optical facility in Japan. This is where our RR-900's and RR-CQLR optics are made. The SOPS-Compact is also made in Japan, but at the Kenko facility. All three optics have or are being used with the US military and other foreign forces.
The RR-Evolution Series is a line of optics that we built for the civilian market. Every optic features quality components like BAK7 glass, all aluminum body, etch reticles, and illumination. The scopes are manufactured at a partner facility in China...one of only a handful of facilities capable of producing quality first focal plane optics. Because we are able to manufacture the optics here, we can offer these riflescopes at an incredible budget friendly cost to the consumer. Each scope whether for the .22LR to the .308 go through three shocks tests equivalent to the recoil of a .50BMG rifle to ensure durability.
We are very proud of all of our optics and offer a lifetime warranty against manufacturing defects. If anyone has any other questions, please feel free to ask! Thanks!

Fantastic! I think that a lot of people think that long distance shooting is sort of exotic. I tell people all the time that it just math, and we put it into a visual format that is easy to translate. Would love to see pics of your setup and results of your shooting!
For all reading this, note that we ALWAYS take care of our warfighters, active or retired, and LEO's. Our discounts are the least we can do to show appreciation for those who've sacrificed so much.

Don asked me to throw a post on here to introduce our optics to the group. At Pride Fowler Industries, we build optics to enhance the performance of the weapon system by giving data to the shooter necessary to precision impacts for the full range of the weapon and ammunition. All of our optics feature a patented ballistic reticle in a first focal plane design for particular types of weapons and ammunition. When paired properly with the specified type of ammunition and weapon, the optic are designed to give the shooter a range, ballistic holdover, and a wind hold which significantly reduces the engagement time and increases precision. Each optic has different attributes that we found necessary to build the ultimate optic for that platform. For example, our 762C Adaptive Combat Reticle found in the US Optics SR8 body, has data for M118LR (175gr) out of a 16" weapon system (MK17) for 0 to 3,000 ft elevation on the right side and for above 3,000 ft elevation on the left side. The left side data will also accommodate M80 ball out of the 16 gun or a 20" barrel change under 3,000 ft elevation. These features give operator an increase in combat effectiveness in the ever changing combat environment. You can find innovative features as such in all of our scopes. Other examples are both subsonic and supersonic data in our RR-Evolution-22LR for the .22LR and RR-Evolution-BLK for .300BLK and 7.62x39. The RR-Evolution-5.56/7.62 which Don will be getting for his Sig 716 has data for 5.56x45 to 600 yards and for 7.62x51 (.308Win) data to 900 yards with accommodations for elevation change and different barrel lengths. We design optics with the warfighter in mind to give them an advantage on the field, but also to give people in all worlds to enjoy greater performance out of their weapons systems by making long range precision shooting easier. We want people not to enjoy shooting not at the typical 100 yard distance, but to become proficient shooters at distances to 600, 800, 1,000 yards and beyond. We believe that this makes for an more effective fighting force for our country. Thank you for taking the time.

Hi, this is Rich from Pride Fowler Industries. We are an riflescope optics manufacturer that specializes in first focal plane optics utilizing patented ballistic reticle designs for military, LE, and civilians. I invite you to take a look at our website at www.RapidReticle.com and our videos on www.Youtube.com. Don and I had a nice conversation about our optics and he suggested introducing myself. Please feel free to field me any questions about our equipment or for general shooting questions for that matter. I look forward to chatting with you guys and seeing our optic on top of Don's Sig 716! Sincerely, Richard M. Nguyen Vice President/Military Liaison RROSM-Pride Fowler Industries Ph: (832) 377-6765 Fx: (877) 893-4502 www.RapidReticle.com
