States that it is for the M4A1, does this mean the bullet drop compensator is calculated using the M193 ball rounds through the shorter barrel?

There are differing answers listed but this is directly from Trijicons ACOG FAQ: "The TA01NSN was designed specifically for the US Special Operations Command SOPMOD M4 Carbine. To meet their requirements, the reticle bullet drop compensator and range finding stadia lines were based on the trajectory of the 62 grain bullet from a 14.5 inch barrel, flattop mount (Picatinny rail Mil.Std.1913)."
1129442
Yes. The standard 55 grain is the factory dial in . Although I am getting much better accuracy w the XM855 62 grain steel core rounds. Not sure why, maybe I'm just getting old and blind.

Hi Stephen - The BDC is calibrated for the M855 (62gr.) through a 16" bbl. Which is weird because the TA-31 series are calibrated for the 14.5" bbl the mil. uses. If you're concerned about using M193 (55gr) w/this optic, your worries are unfounded; this optic will deliver tight groupings using either the M855 or M193. If you're ''on the fence'' about this particular model, jump off that sumbitch and get it; I prefer the TA01NSN over my other TA-31s (A4 & M4 RCO models). Any other questions, don't hesitate to drop me another note... Best Regards, Tim p.s. I also have an Elcan DR Specter and I'd still grab the AR w/the TA01NSN sitting atop it; it's built like an Int'l. Harvester...

It should, you might have received the wrong barrel. The threads are supposed to be big like the stock barrels on 98 receivers. The Alpha Black and Project Salvo are derived from the Tippman 98 Custom receiver. Therefore, aside, from aesthetics, the Alpha Black and Salvo are internally identical to the 98 custom.

...barrel and stock lines seem to be slimmer and very much lighter (compared to 10 pounds or so) but it has been over 40 years since I had an M-14 in my hands: it is all plastic except for the barrel and internal receiver parts. Get this...the bolt actually opens and closes when firing. FYI, it looks real enough for the Sonoma County Sheriff's Deputies to kill you for holding it.

No, it only fits the HFC M11. Possibly other similar M11A1 makes by different companies, but it certainly would not fit on an M4 or other rifle or pistol models.

No. It works by creating spin, like a curve ball. You wouldn't want to do that to a first strike round. You're better off with a rifled barrel.

The powder drop has different length parts to reload different bullets btw.

Yes it can. Good news too. If you go to Nikons website for this scope you can find the ballistic tables for your specific caliber and ammunition load. That will allow you to use the bullet drop compensator are circles in the reticle. It would allow for precision shooting long distance.

No it is not ... There is a adjustable rear sight and adjustable front sight atop the barrel . Honestly with this plinker sometimes you have to shoot a little left to hit right . A fun gun , accurate ? hmmm ! I think they forgot about that equation.

Yep. All in all this was a very poor design. Did not for my full mil-spec m4 at all. I couldn't use this at all.
160527
Yes. You can get the next version of it with drop compensation as well. I prefer this reticle/optic for close to mid range engagements but if you wish to engage past 300 meters get the one with drop comp

If I remember correctly the 17lb spring is the same as the factory, or very close. The other spring weights while affecting recoil I think are really to match the bullet weight of the cartridge, i.e., the heavier the bullet the stronger the spring. I have the 17lb spring and use a cartridge with a 115gm bullet and it works fine so far.

It is the short barrel. I had the same question when I purchased the rifle.

Not sure if it functions as a "flash hider" as I never fired it at night. It DOES work as a compensator and slightly reduces felt recoil. If you order this item cake sure the one you receive has a bore hole NO larger than 0.250 - 0.260" I had to send the first 1 back as hole was for a 308 rather than a .223
1151577
Yes it will. It was developed for the Win. .308 rnd. for the M14. I have one mounted on a Barrett .50 Cal. and have had no problems so far, two years use.

No, this one is for the G36 type airsoft gun. You need to look for the one's designed for the m16 magazine well.

No, it was designed specifically for M885 nato ammunition for either an M4 (zeroed at the 350yard elevation line) or the M16 (zeroes at the 300yard elevation mark). The elevation markings are designed for this specific trajectory and while similar bullets (ie 55gr FMJ .223) can be used with little difference on a AR15 w/ a 16in barrel; i do not believe that a .308 bullet will be very effective using the elevation markings with the Matech rear sight.

IT IS NOT A DROP IN KIT. This is a great upgrade but it does require some modification. Check out YouTube for a good install video. As for the firing pin, it comes with both 4 & 6 lbs springs. The longer one is the 6 lbs spring.
