2020年9月22日 · 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.

2022年10月15日 · 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.

2016年8月6日 · 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.

2019年3月3日 · 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 ...

2024年5月2日 · 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 …

2015年4月27日 · Bogy hopefully with BigRix help you can mate your ArmaLite scope to a AR-18/180 base. The ArmaLite base has no markings other than the early inverted post scopes models having serial numbers starting with 67 and 71 that also denote the year of mfg by Hakko, later scope bases had no serial numbers.

2025年3月6日 · Developed as a successor to the original AR-15, the AR-180 was a civilianized version of the AR-18, itself an upgrade on the M16 platform. The BRN-180® incorporates many of the AR-18/AR-180 improvements - including its robust and reliable gas piston operating system. (Yes, the originators of the AR-15 / M16 eventually embraced a piston!)

2021年2月9日 · Rick remember reading about the Numrich Sterling AR-18 parts kits that were sold and only the lower was cut at first if memory serves me right, must of been 20-30 years ago. Possible they came from Africa and had more than one owner, any sand? Nice find and agree with keeping the well used look. Maybe someone at Numrich can fill you in on the ...

2021年3月19日 · If you have a particular recoil impulse you are looking for on a shot or shot to shot basis you can run a buffer style or weight that will give you that and then tune to it. If you dont trust an an adjustable, I ran a Criterion 18" rifle gas with a Lantac ultra low profile block, and a JP SCS with the standard spring.
