2022年10月15日 · Depends on what your doing with the rifle. If your making things dead, go 18". If your shooting as fast as your capable, go 18".

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.

2011年4月8日 · 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) then I …

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.

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 ...

2016年9月7日 · I believe the time line of the ArmaLite AR-18/180 goes something like this, the Costa Mesa rifles (AR-18/180) started to be mfg in sufficient quantity starting in 1969 and continued thru 1972, roughly 4,000 AR-180 and around 1,100 AR-18. Something rings a bell re the Howa AR-180 that they got the green light to be exported from Japan in late 1972.

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 ...

2017年8月21日 · I figure if folks want an 18" barrel, they probably want it for longer-distance accuracy from the increased velocity, and a heavier profile stiffens the barrel to prevent it from opening up the shot groups when the barrel heats up.
