2022年1月6日 · I have been using flip BUIS since they hit the market in the 1990s. I've used GG&G, MI, ARMS, MATECH, Troy, Diamondhead, UTG, MagPul (MBUS and Pro), YHM, Mepro, SIG, MFT, Samson, LMT and KAC.

2017年12月15日 · The spring tension is weak enough on the KAC BUIS, that you can do a finger flick and the sights will be folded. I have 5 SR15 rifles w/ KAC BUIS, and 2 more sets on my other AR, and they are all like this... The Magpul Pro seems to be just right, stronger tension than the KAC, and not as stiff as the Griffin sights as you mentioned.

2011年5月18日 · If you really want a KAC BUIS and need it now, then you may be stuck with the 300m as the 200-600m are going to a USMC contract. That said, a quick Google search found them at topnotchtactical.com, but it's hard to tell if they're in stock or not. I have only used the 200-600m, but I would expect the 300m to be very sturdy.

2019年10月7日 · Just received a KAC BUIS, what do you think? It looks fake, I have a real one from Charlie’s Customs and it has the USMC and KAC symbol etched into the sight. The one II just received has USMC stenciled onto it. It looks like a really good fake, but I just can’t tell, Did KAC ever stencil their logo onto their sights? Attached File

2015年2月3日 · KAC 2-600 is the best rear sight on the market especially when paired with the KAC micro front sight. KAC is the only BUIS I will buy. Posted: 2/3/2015 4:37:50 PM EDT

2020年5月28日 · Everytime i purchased a new set of KAC buis set i swore they were taken off from a gwot rifle back to armory into a new packaging. They are great though. Posted: 5/31/2020 1:04:36 PM EDT

2018年7月8日 · I know KAC makes great stuff, but I won’t own buis that don’t lock in the up position. Troy is my choice, and the standard flip ups can be had for $100-$120 a set during Black Friday or sometimes used in the EE. Ymmv Magpul polymer sets are good for …

2017年4月5日 · The KAC 600m is calibrated for a 20" barrel with M855 FWIW. If this is an iron sight only gun and you are wanting to shoot distance you should use a detachable carry handle or fixed BUIS, the KAC 600m does not stay up. I use either the LMT fixed BUIS or Rainier Arms/ERA-TAC folding BUIS (the best folding BUIS available IMO).
