I stock the JPoint and special order the Dr. I am a right handed shooter and put the JPoint on the right side of my scope. C4 www.GRTactical.com

Thanks C4
I checked your site but didn't really see much info. Who is the manufacturer of each or where can I go to compare/contrast the two? What's the main difference in the two? My searches didn't turn up very much...not many people must carry these. ETA: Found this...pretty good info. Do you all know of anything else? www.jprifles.com/ ETA: Just a few more questions... What is the power source on the JPoint? If battery, what kind of battery life? What type of on/off switch? Sorry for my ignorancein this type of optic.

just my .02
I know they are hard to find but they are out there, and I do know the difference between the Doctor and JP is: then JPoint is made out of a type of plastic and the DR is made of aluminum and more durable which is why you will see more military and LE using them. |

The Doc Op is made from machined aluminum while the J-Point (a slight improvment from the Optima 2000) is made from plastic. The other difference is clarity of the glass and dot of the Doc Op over the JP. The doc-op utilizes two highly polished, optical quality glass lenses (compared to one plastic lens in the JP) sandwiched together and solidly set in the frame of the sight. Over several years I and other LE Depts. in my area have shattered O-2000's and JP's during bang-ins with walls, i.e. corners and such. The farily new JP winged protective shroud helps in these areas, but for complete durability I feel the Doc Op is the way to go. The Doc Op comes in two variants, the normal and the Mil-Spec version with either a 3.5 or 7 moa dot. At $600.00+, don't waste your money for the mil-spec version unless you need to submerge the unit. The only other difference I am told is brightness between the two. I have all three systems, and all three are about the same brightness. The Doc-Op maybe a bit brighter, but only slightly.
The Doc-Op Batteries consist of standard lithium Type CR 2032 3-volt battery. A supplied hood shuts down/dims the dot The unit has a built-in "Battery Save" mode which extends average battery life to approximately three years. Here is a pic of the JP winged unit as I was working with a ACOG system.

There two major differences to me are cost and materials. Both optics will serve you well. I personally run two JPoint's and have for several years now. I also sell a lot of them and have had ZERO returned for any issues. I also sell them to Military guys in the sand box and they are also an issued item with some SF groups. C4 |

Does anyone know if anybody makes those "wings" to add to whatever mount you already have. The mounts I've seen are a one-piece unit made for certain applications like the ACOG, AR-15, Mossbergs, etc. I would like to add those "wings" to my Larue SPR/JP mount. Any help would be great.

There are actually four assertions, not two, present in SIMPLYDYNAMIC’s post. 1. The DR is made of aluminum. 2. The DR is more durable. 3. More military use the DR. 4. More LE use the DR. Do you disagree with all four, or only two of them? I have read Grant’s post a half a dozen times and do not see him contradicting any of the above four assertions. Maybe I am simply dense and am missing the point. Could you clarify this for us? viator |

Since my comments are the topic of discussion, I will respond. I have sold more JPoint's to Military/LE/Contract shooters than I have Dr optic. I have yet to hear of one breaking. I also personally run the JPoint and have never had any issues. Buy what you want, but don't think the JPoint is a fragile item. C4 |

It would be dumb to question that assertion.
There is no evidence to support this assertion.

So both the Doctor and JPoint are rugged enough to be aggressively used off the edge of a belt, kydex holster, boot heel or other hard cornered object for one handed techniques? If so they are a lot more durable than I first thougt and I might have to consider one on a future pistol project. |

How tall is this combo? I wasn't sure if the DR would clear the fiber on the front of the ACOG.. I think I am going to throw that combo on my AR-10 Carbine. -C4- |

Which do you suggest for the JPoint on top of an ACOG - 4mm or 8moa? Thanks |

The JPoint makes some small risers that can be used to gurantee that you will clear the fiber. C4 |

Well that is really personal preference. I generally like to use the JPoint from 30rds and in so I am fan of the 4MOA dot. C4 |

From the JPoint page:
"A common question about the JPoint is "How does it compare to the Doctor?" Every sight design represents a compromise between various attributes. The Doctor has a metal body and glass lens and is considerably heavier. The glass lens of the Doctor is more optically perfect than the acrylic lens of the JPoint, but adds to the weight. The acrylic lens of the JPoint will have some minor optical distortion that is apparent only under intense scrutiny such as holding the sight up to a light and focusing on the lens. When you're actually shooting, you're never focused on the lens so this distortion isn't noticeable in live fire conditions. If you're focused on the lens while shooting, I can predict you're not hitting your target. The extremely low weight of the JPoint makes it ideal for applications such as our shot gun barrel mount and piggy back scope mounts which attach with a special adhesive. Low mass translates into low inertial effects for slide mounting or adhesive mounts and the sight/mount system will stay put under extreme conditions. The JPoint is also considerably less expensive than the Doctor and there are many more adapters from several sources for many more applications than are currently available for the Doctor. The JPoint is not for every body, but is a great concept for a wide variety of applications." |

Hello,
I have mounted both Jpoint (Optima 2000) and Docter Sights to pistols (competition, i.e., steel plate, IPSC). Like many of you, I questioned the durability of the sights. I started with the Jpoint-Optima type sights, and then transitioned to Docter Sights on my more recent builds. I have found both sights to be very reliable. Once securely and properly mounted, I have found no significant drift or loss of accuracy over time. Keep in mind that with slide-mounting the sights, they get battered quite a bit--certainly much more than with routine shooting from an AR-15, where the sight is mounted to a rail or to another sight/scope. However, being a competition shooter, I can "be careful" with my guns and I don't routinely bump my sights against doors, barricades, etc. I did ruin an Optima sight once when a little Gun Scrubber got away from me hen Because of this, I would think that the mounting systems that provide "side wings" may be a better choice for mounting these sights on rifles that may see hard use. I have a Jpoint mounted on an ACOG using JP enterprises mount. For those mounting systems that place the Jpoint/Docter on the side of a scope, it might be nice to have a single "wing" that protects the outer/exposed side of the sight from being bumped. Just some thoughts. |

When comparing sights i also look at customer service. I emailed JP and Dr Optic (last US distributer and Germany) I got a quick responce from JP, Germany took about a week (no big deal) and the last US dist for DR Optic I never heard from. From what I understand, their is currently NO US distributer for the Dr Optic.

The more I read the more confused I get... Is there a difference between the Optima 2000 / JPoint / Firepoint? THese terms seem to be interchangeable on some websites and others speak as if they are all similar but made by different manufacturers. Thanks again for the help. |
