Oct 15, 2022 · An 18" BBL is more than half thE performance difference between a 16 and a 20 (extra length has demisinshing returns, the 2" address on top of 16 is more meaningful than another 2" adder to 18). 18" Gunner is actually a pretty fantastic default standard profile to run a generic general purpose AR15.

Aug 6, 2016 · A 30-shot string of Hornady 5.56mm 75 grain TAP T2 chronographed over an Oehler 35-P chronograph from a Noveske 18” SPR barreled AR-15 had an average muzzle velocity of 2779 FPS; for a difference in muzzle velocity of 44 FPS.

Sep 22, 2020 · As I understand it, the AR-18 was supposed to be a cheaper, easier to manufacture alternative to the AR-15 for smaller countries looking to equip their armies with a locally produced rifle. The problem was that the US government was happy sell AR-15s cheap or flat out give them away to client states.

Oct 15, 2022 · I make AR-18/AR-180 mags out of Pmags and USGI mags. Easy to do. This post is not about those. I noticed that Wilson Combat sells their AR mag with an AR-18 cut already in place. Very strange that they did this. Where it is only can serve one purpose and that is the mag catch on the AR-18.

Mar 3, 2019 · Probably not, AR-18's/ AR-180's have always been pretty darn accurate, and are just modified AR-15 barrels. They would have to have use a pretty garbage barrel to have disappointing accuracy, plus all the rest of it's all AR-15 stuff, so any drop in trigger will work too (that doesn't require an AR-15 bolt) so there's a ton of match triggers ...

Mar 17, 2017 · But the AR-18 patent is long expired and it sure lends itself to the kind of layout the market seems drawn to buying. Heck, the original was even a side charger I think. As hard as some smaller companies work to "innovate" with minor tweaks you'd think someone would have come up with an upper compatible with AR15 lowers by now.

Nov 2, 2024 · An 18” with that load will get me maybe another 50 yards for that velocity. 16” is my vote unless you are okay going 14.5”. I have killed dozens of average to large whitetails with 77 TMK from an AR.

Apr 8, 2011 · I feel optic and ammo choice are far more criticle than barrel length. in my opinion a "recce" type build (16" barrel w/rifle length handguards) with a 1-4 optic with a ballistic reticle is the perfect balance for the 5.56 ar platform. run buis rather than the 45 degree setup. on my recce I sighted the back up irons on M193 ammo (most common ammo thats easy to stack deep) …

May 2, 2024 · I have personally been gravitating towards the Leupold MK5HD 3.6-18 and the Nightforce NX8 2.5-20 for my longer (18"-20") gas guns. Completely agnostic of the specific make and model, that general magnification range seems to …

Mar 22, 2008 · My friend has a shop and a fellow wants to sell him an Armalite AR-18 with two Armalite magazines. The various books go from like $1,100 - $1,500.
