Tommygunn Posted July 25, 2006 Report Share Posted July 25, 2006 7mm bearings provide faster ROF than 6mm bushings. Where did you hear that? Bigger the bearing the greater its resilience so they are and able to handle greater stresses over a larger area. Link to post Share on other sites
bepo Posted July 25, 2006 Report Share Posted July 25, 2006 (edited) Just got my brand new ISC m4 Ver3. Right out of the box I added a madbull 6.03, hadguard rail, and i have a tac light i'm going to put on it (a friend has it atm) Added a scope and bi-pod for a bit of counter sniper action The wierd thing is, no matter how much I look at it, the front sight still looks in the way of the scope, but when you look through it's clear, nothing blocking it. ~Bepo Edited July 25, 2006 by bepo Link to post Share on other sites
tgrillo Posted July 25, 2006 Report Share Posted July 25, 2006 ehh, the scope is a bit big for my tastes, but if it works well for you more power to ya Carbacca, I'm liking the m4 in the second pic Link to post Share on other sites

bepo Posted July 25, 2006 Report Share Posted July 25, 2006 that's awsome Oleander I added the scope because its the only optic I have right now, but i'm getting an aimpoint soon. It is too big, but you need to make do On a side note, i just did a fps test using the poor mans chrono and I got about 360-370 fps, after only installing a tightbore. It went through both sides of a can, and almost went through the bottom (it made a slightly smaller hole) I'm leaning to say it's like 370 fps, which exceeded all my expectations. ~Bepo Link to post Share on other sites
davedawg123 Posted July 25, 2006 Report Share Posted July 25, 2006 Where did you hear that? Bigger the bearing the greater its resilience so they are and able to handle greater stresses over a larger area. <{POST_SNAPBACK}> I never doubted this. Milla asked what makes 7 better than 6 (this is a little vague, since there's no mention of bearings or bushings). If Milla was referring to just the difference between 6mm and 7mm bearings, then you are correct. On the other hand, if my presumption that he was referring to the 6mm bushing and 7mm bearing gearboxes of CA M15's I mentioned just above his post, then yes, 7mm bearings provide faster ROF than 6mm bushings (as well, you are still correct). Bearings provide faster ROF than it's rigid bushing counterparts, however, bearings aren't as resilient to load. Thus, 6mm bearings can't handle heavy loads too well before failing (compared to 6mm bushings), so 7mm bearings are used instead to preserve it's ROF advantage over the bushing while providing greater load resilience than the smaller bearing.

Milla Posted July 25, 2006 Report Share Posted July 25, 2006 Thanks dave, you pretty much told me everything i need to know lol. Anyway i chronoed my stock CA M15 and it shot a steady 320fps. I just added a tight bore barrel systema 6.04. No idea what its shooting now lol Link to post Share on other sites
Tommygunn Posted July 25, 2006 Report Share Posted July 25, 2006 Actually, now you mention it I didn't take note that you said 7mm 'bearings' and 6mm 'bushings'. My bad. In any case I'm sure you agree that the bigger the load medium(see below) in physical size, whatever its make-up, the better its ability to take a battering. As a side detail I have always considered 'bearings' to be ballraces(RC car term) and 'bushings' to be bushings(plain bearing in essence) while the term 'bearings' I have always considered the generic name for the whole lot.

davedawg123 Posted July 25, 2006 Report Share Posted July 25, 2006 (edited) I agree. Larger bodies tend to spread the load, distributing much of the stress concentration points of smaller bodies. I've made the same presumption of bearings and bushings myself. The bushing nomenclature seems to be rather general when others have described them for airsoft use, being used to describe both bearing and non-bearing axle spacers/cushions. I even see many airsoft retailers making the same type of descriptions. So naturally, I was a little confused at first. And I'm glad I could help, Milla.

trfo2o Posted July 26, 2006 Report Share Posted July 26, 2006 why? is it because of the flash light? or aimpoint mount? what? Link to post Share on other sites

Also Close Quarters Defence makes the rear sling mount. They are also issued with grips that have no finger rest. Other than that she's the same.
