A1/A2 flash hider question
Is it possible to take an A1 or A2 front flash hider and bore it out large enough so that you can use it on a 458 Socom build?
More importantly will it have the structural integrity and thread holding capacity needed to stay secure on the threads?
I'm looking at doing a retro type carbine build and want it to appear as a normal small bore AR, thats why I am asking.
That and the fact I dont really like the look of the more modern flash hiders on the market.
The threads are probably different sizes between what's on the barrel and in the f/s. But RRA sells an A2 with the larger threads. (eta: it's for their 6.8 SPC rifles.)
Next, flash suppressors are hard. I used one of the RRA units on my .45 ACP carbine and my gunsmith had to mill it open rather than just drill it. This is plenty strong for my application but I have no idea how safe it would be for .458 SOCOM.
fwiw, the 9mm guys open up 5.56 flash hiders all the time.
Thanks guy's, I'll give it a try. Who knows it just might work out alright.
The 2 radial grooves at the rear will limit how big you can bore it out.
Measure the minor diameter of the grooves and compare that to the major diameter of the thread you want to use.
I would want at least .030" wall thickness for most applications, and bigger for that caliber.
I gotta say Mike, Thats a great bit of information but unfortunately it's totally wasted on me as I havent got the background to understand what you just said.
But I know it has to do with a caliper and how thick something is. My shop classes dealt with wood back in the 70's. So I have a very steep learning curve to try to catch up enough to even begin to understand the language some of you speak.
but it's sounds like you just told me "No it wont work because you wont have enough metal left after you bore out a 1/2" hole."
Which means I will have to find someone to make one for me when I finally get that far along.
The 762 Vortex can be done like that.
I'd recommend getting a YHM Phantom flash hider in .45acp. I'm using one on my CNC/Khalan/Olympic AR45 right now. It's set up with acme threads for a quick detach for their supressor. I live in MA, so I can't have supressors anyway, so I removed the retaining clip, spring and retaining ring and turned off the Acme threads. That way, I have a short Phantom for my .45 that I didn't have to bore out and worry about thickness of either the hider itself or having adequate threads.
Here's a link to the hider:http://yhm.net/index.php?main_page=product_info&cPath=2_7&products_id=115&zenid=00c9df0ebe2aba9490e585fa3f1627be
It's not exactly a retro look, but it's not really an ultra modern look, either. It might be a good compromise for your build. I'll post a pic in this thread tomorrow when I pick mine up. It has more of a retro look after removing the supressor hardware and turning off the Acme threads.
