Geissele 14.5 SD Upper initial impressions

[Hank6046]

Finally got my new Geissele SD 14.5 upper in on Saturday and shot on first thing on Sunday (7/24/22) , put around 100rds down range and it seems to be very accurate right out of the box (shooting out to 50 yrds). The bluing or proprietary finish is a little different, as the upper seems Blue-Gray to the rail, which is more of a standard black you have with DD, SOLGW, AERO, etc. It is definitely a quality upper, everything seems like it was inspected and put together to the highest standard. It did come in a oily film of some kind that I wiped down upon opening. I was just shooting mixed 55gr (Armscor, Aguila, PMC). I put this 14.5 Geissele upper on an existing ADM complete lower that I've had for probably 4 years now, it replaced a DD v7 upper, which I really liked but felt that the 16" barrel with a Warcomp was a little long and unwieldy for a GP carbine. Obviously I need to shoot it more but it does feel like the weight is still there with the profile of the Geissele, but a shorter barrel and rail are noticeable when your pointing it. So shot the Geissele upper along doping my original DD V5 with a PA red dot and My 16" BCM ELW BFH upper on an Aero lower, all in all they all shot pretty well the Geissele seemed a little more pushy, not necessary punchy but my DD and BCM have the BCM Mod O comp and considering it is just a flash suppressor I guess I've been a little spoiled on compensated muzzles.

Went back out with targets Sunday (7/31/22) and had a lot of trouble zeroing my Acog at 100yards, some 3 shot groups were well within 1moa and the others where well within 2-3 moa. Part of this is the fact that I tend to zero with a leadsled which my father in law currently has, and it was clear that my Acog with a kram mount and ADM mount needed to be loctited down further. I tightened them up as much as possible and shot some decent groups but not as accurate as I feel was possible from the barrel. The other issue was the ammo, shooting the same ammo can with Armscor, Aguila, PMC, and Fenix I think that they are all different enough to produce different results. While in the 230-300 rounds I did shoot I didn't have an issue at all with the performance of the gun. I want to zero the rifle to 62gr, or 77gr which I need to get out and buy a few boxes and post my results on each as well as I want to put on different glass with more magnification to help verify what accuracy I can expect overall with this upper as baseline.

Trying to add in additional Pics but they are too big. I'm horrible at this, but am working on getting them on for everyone to see.

Hello all,
I have gotten a text from a very good friend pointing out how everything posted above makes me look very dumb this makes me look and I agree, but I remember so many people on here posting about their rifle and the accuracy of their post that I was indeed most likely the error at fault and deliver you my actual results because (1.) I hope to actually push my real world knowledge on everyone, and (2.) I hope to to be accurate in my postings. If the fault is mine, then so be it, but I don't want to falsely claim that my Geissele 14.5 SD upper is in accurate when it is in fact not and that the error is most likely of my own making. I hope that this (M4C) remains a place where the content is transparent and we can all benefit from the lessons learned, and that in this case I was not quite the Scout Sniper wantabe with an Trijicon ACOG as I remember myself over 10 years ago. I think I'll end this thread here on my end unless anyone has any questions for me and the process I went through.

You don't look dumb, you look like you kept an open mind and learned something. I thought it was interesting, anyways.

You'd look dumb if you refused to try anything else out and argued about it.

Hello all,
I'm resurrecting this thread as it has been about a year since I have posted on my Geissele 14.5 Super Duty upper mated to a ADM complete ambi lower, I've probably got about 2k rounds through it thus far and plan on posting some groups sizes, all of which has been shot with the aforementioned ACOG and Holosun 509T piggybacked on top. It hasn't been shot an amazing amount over the past year (maybe 800-900 rounds) but it has been dropped on concrete multiple times (thanks to my 9 year old), has been pretty gummed up from a mixture of sand, pine sap, and budget brand bug spray and ran and managed to run against some notable other brands. All in all it has continually posted better and better groups out of it (this I hope to show soon).
