not anymore then the other models.
If heat is such a big issue, then i would be worried about having bolt on side rails made of material that is not the same as the body like the others do. As different metals have different heat flex points one may move the other when it expands. I dont actually believe this, but just pointing out the flaw in the logic introduced earlier........... i still dont understand how adding more material just to have vents is a good idea. From a side profile they are all similar in that neither allows air flow. With vents across the top you are either introducing the gas system to the external environment or the piston is covered and not different then mine. the only difference is that mine is Canadian made, lighter and lower as well as easier to removed.I would also be concerned about the ability to hold zero when you are having to bolt the unit together every time you want to clean them. To many surfaces to hold dirt and debris and throw things off.







will it have side rails?

It can be drilled for them

The distortion is a relative thing. Keep in mind that the barrel is rather thin so as the barrel heats up POI will begin to string as barrel whip increases no matter what you attach or don't attach to the gas block/trunnion area. So you will have a mild distortion in any aluminum hand guard mount as the heat in the gas block is bled off onto the aluminum. The only system that I've seen that won't distort as much is the FAB aluminum hand guard but it bolts together making cleaning difficult. Either way we're talking about a very marginal amount of distortion and when natural barrel whip increases the distortion of the hand guard is not going to be a huge factor.

As CM said this design has minimal material meaning faster heat dissipation and reduced overall distortion due to it design and the allowance for barrel movement. If anyone is willing to do a shot for shot test against any other hand guard I challenge them to post up the results.
 
From what I understand FAB is no longer shipping their hand guard for commercial sale pending redesign, they were after all initially made for a military contract. The upper portion of the FAB ones only fit the non stepped gas blocks which I have yet to see on any Canadian rifles so I would suggest that the FAB unit as it is now is a non starter.

I dont see how you think the venting on either of those makes a difference. Basically they have added extra material to have vents which will conduct more heat

less material (ie 1/4 inch aluminum) will heat up faster,hotter and expand much quicker then more material (ie 3/4 inch aluminum) with the same heat applied to it...... It will obviously also cool faster. The vents in the upper mainly clear the gas where the upper mates with the lower.

Anyways if you want to run your rail through its paces I can put you in touch with a buddy of mine who is serving in the Czech military. He also runs gunexpert.cz . He can do and record an unofficial test with their service VZs.
 
I'll take this one then.....and the straight stock adaptor.

LOL that is the FAB one but I modified it to fit that VZ independent of the upper HG. Either way this thread isn't about my toys its about NEA's new product.

It will not be hotter as it is dispersing heat faster. And it will not distort any more then the other models. As i mentioned before, the brugger model still wraps around the piston. Basically they have added an extra 1 1/2" of aluminum vertically so they can say "i have vents". Congratulations. When my upper mates with the stock wood or my lower there is a gap that "clears the gas" ( check the first pics posted in this thread). the only difference between mine and the infratek or B&T model is mine doesnt require a set of tools to take it apart for cleaning.

Im willing to put the year of testing and advice of Aircraft engineers up against hear say on the web. Aluminum has to heat up far past what high volume shooting will do to distort to the point of making any of the hand guards inaccurate.

My lower that is coming out soon is vented just as much as the others on the market.
 
Can't say if this is a "heat distortion" issue or not, but the Dlask rail's latch goes from tight to floppy loose when shooting.

That doesn't happen with the NEA design.

I’m not arguing with you or your “aircraft” engineers that you didn’t put thought into your design. The MTC rail that strangely only Stevo is having so much trouble with took 2 years to design by MT Corp who only deals with the Slovak Government/Military and just like the new B&T rail, only requires a allen key for the initial setup because as mentioned before there is slight variations in the rifles. After that neither of them require any tools to clean. B&T mates with the lower and has gas vents. MTC/INFRATEK just like yours doesn’t mate with the lower and vents out the side. Look the bottom line is that to make a low profile rail or to make the front tabs as thin as yours is not a problem and have been avoided for certain reasons. I’ll order up one of your rails and send it to my friends at VTÚVM Slavičín and if it holds up you could have a lot business come your way.

Thank you for the offer but i would prefer you didnt. We are already working on a distribution deal through a source in eastern europe and having the NEA rail show up through a second source for critique may derail what we already have in the works as it will make me look dishonest. I have given them my word that the rail is theirs to distribute outside of North America and i would prefer not looking like a rat weasel. Your welcome to buy one though and post your thoughts as its a free world.

VTÚVM Slavičín can still test it....and if they like it, they can buy from your choosen distributor.

Correct me if im wrong but they appear to be a manufacturer? Why would they want to send me business and for that matter why would palinak unless he is looking for a marketing job with NEA which would be silly considering he has his own line of competing components.

So you're implying that because of my honest review months ago for your rail I must be suspected of.........what exactly? I reviewed yours in January, I got the NEA rail 10 days ago. Never heard of MTC, is yours a licensed copy?

Did you not see that I was happy with it after I got it set up? *Edit* I see that my review thread was edited to hell, so I guess you didn't see that.

I've recommended both rails as good product to guys that have pm'd me. Strangely, I still recommend your product even after your horrible customer service and difficulty in setting up your rail. I wonder what that means?:rolleyes:
 
Just recieved my top hand guard from gp tactical.NEA MOUNT LOOKS GOOD AND FITS WELL.MOUNTED A STRIKEFIRE ON IT .IT SITS NICE AND LOW.I LIKE IT !GP IS GREAT TO DEAL WITH.NICE PRODUCT NEA HOPE TO SEE MORE OF YOUR STUFF SOON.
