      I'm not sure man. I don't know what the 1 1/16 or the 15/16 would mean then if 3/4 of an inch is what we're supposed to match it to.

        I think the 1-1/16" is the one you would order if you had a heavy barrel (stainless bull barrel, etc...). As you have the standard barrel, the 15/16" is the one you want. If I am wrong, I apologize. I am just interpreting it the way I see it. Call to be sure.

              Probably a question for mod., but yes, very irritating.

              • Hi Jwise,

                Read and re read your forum post. Very helpful. Built an upper yesterday from parts at the local shop which happened to be Rainier Arms (seems like a great shop), then went back and bought the upper kit. Spent more than I had wanted to because the best upper kit that -- 1) had all the specs you mentioned and 2) was in stock -- had free float Daniel Defense Omega 9 rails so added $300 to cost but I thought it was a good system and adding it later means taking barrel off.

                Bought a box of 500 Federal 55 gr and went to range (only had 25 yard range) excellent rifle, groups tight even though I am not a pro. Had to adjust windage and elevation a few clicks. The rear sight is OK but would like something different. Will have to wait on the red dot sight. I am into this a bit more than I wanted to be, don't want to upset the boss too much more than she already is! Shot 100 rounds and these pictures are of dirty rifle, sorry!

                • I'm thinking of going with the Troy Tritium Rear Folding Battle Sight instead of the fixed DD rear sight. I figure I'm going to eventually get an optic and would like a fold down one then, so just as well spend another $30 for a quality sight. Here is the link to the sight, what do you all think? BCM shows good reviews of the same looking sight without tritium.

                    That rifle is slick! It looks like its got everything you need on there, plus some style points for the CTR & MIAD grip! I would strongly suggest learning to use the sight as is. It is a quality unit that is well suited for the job.

                    Excellent purchase. It will serve you well.

                    • Thanks Jwise, there was a vertical grip left out that Daniel defense is sending me for free. I think I prefer to hold barrel.

                      I am trying to zero the sight and am trying to figure out how to do that. It is a combination of a1 and a2 style. It has apertures of a2 style but windage adjustment of a1 without any elevation adjustment. That is what I don't like. I would like elevation adjustment for distance.

                      At the range I had only 25 yd range and so using the small aperture got it zeroed to be sight picture on target groups ended up a few inches low. Which as I understand it is due to rising trajectory.

                      I did not realize that the aperture might have some compensation for elevation. At 25 yds I should have been using the large aperture. Should I then adjust front sight elevation until I am on target or let it be low and adjust my sight picture based on distance as I do not have elevation on my rear sight as an a2 sight would. So can not adjust sight quickly for range.

                      I am not an expert on this. I was given some diagrams about bullet trajectories and the rise and fall of bullet. I would like bullet to go where sights are aimed and not have to do a lot of compensation for basic shooting. I understand if I was shooting 300 yards then it is more complicated.

                      I was pretty pleased that my groups were pretty similar and accurate from standing and the bench. This is my first rifle. My other weapon is an HK USP 40.

                      • First off, elevation is dialed in with the front sight. The sight is not supposed to be a target sight, but a combat sight. Adjusting for range is not the purpose of the DD or LaRue sight.

                        As for sighting in a sight like this, you need to decide what distance you want your weapon dialed in for. Frankly, I think you should zero your weapon at 25yds.

                            While I totally agree with jwise on the first part, I'm going to have to disagree on the second part of this post. I prefer a 50/200 yard zero, as described in the below attachment:

                            http://grburnett.us/guns/ImprovedBattlesightZero.pdf


                            There was also an article in the October 2008 edition of SWAT magazine entitled "BATTLESIGHT ZERO - Who Has It Right?" by Lt. Col. Freddie Blish, USMC (Ret.), which compares four different setups. I have the magazine at home, but you can buy a pdf copy here for about $5:

                            http://www.swatmag.com/content/issue.../october_2008/


                            The gist is that with this zero, from 0-250 meters the POI will not differ from the POA by more than 2" high or low.

                            • Yes, but you forgot one KEY point. He only has access to a 25yd range. Given that parameter, sight it in for 25yds. Otherwise, the 50/200 zero is preferred over the 25yd.

                              • Point taken, but if at 25 yards he sights in for POI to be 1.5" below POA, he should be just about on at 50/200. (that 1.5" is off the top of my head....can't pull up the trajectory chart right now).
