Quote HistoryOriginally Posted By krdt:
Nah... a FA safety is no more likely to end up in a position you don't intend than a semi-auto safety is to end up going from safe to fire. Both are held in place by nothing more than the detent; the only difference is, the FA safety can move to another position and potentially past that if you force it out of the detent hold. Functionally, you'd never notice the difference unless you intentionally move it to the third position or beyond. The only mod that's (debatably) required is a small metal "fin" that needs to be milled or ground off (designed to push down the SA disconnector so that the auto sear can engage). You can do it in a few minutes with a Dremel. Technically, if your gun isn't FA, it isn't FA - whether you use a FA safety or not. But, in the unlikely event you ever had an FCG malfunction, it'd be better to show you took affirmative steps to render the FA safety not suitable for use in a select-fire. I've got one and it definitely goes 360... no hard stops. After all, it was designed for use in lowers with selector stops, so it does make sense. I mean, you could put a couple of tack welds and stop it, but I don't see much point. Quote HistoryOriginally Posted By krdt:

As mentioned, if using the FA version, it'd probably be a good idea to shave the "fin" to make it a true "semi/semi" safety. Not that an unmodified FA safety is going to turn a semi to a full auto, but just for the sake of not using any FA fire control parts. ETA: I guess I should add that if you use a FA safety, you'll also be able to rotate to the 3rd position (safe/semi/semi). Kinda nifty, I suppose. Actually, if you're using a lower without selector stops, you'll be able to rotate a full 360 degrees, lol. I mean, you could put a couple of tack welds and stop it, but I don't see much point. |

Changed me some optics around last night. Moved the EXPS to the 416. Got them pretty dialed in today. The CQBR is heavy but damn does it shoot well with the 1-6.

Hey guys. How acceptable is a Surefire m600c scout on an mk18? Were they ever deployed and used? Mine currently has a black m3x long gun but also has a few other “non standard parts” such as CTR stock and hogue grip. It’s also a black f**k FDE theme. Oh and please don’t flame me for the fake PEQ because I can’t justify the cost of a real one for something I will never really use. Lol
