Afterward, we installed the YHM AR-15 free-float handguard that I've had ever since I bought the AR parts kit from Del-Ton. It was actually significantly easier to install than I imagined. The most difficult part was breaking loose first the flash hider and then the barrel nut. I'm really pleased with the handguard so far.
I went ahead and pre-ordered the Burris AR-332. After doing a little more research, it appears that SWFA are scheduled to get these in around February 11. I'll do a review once I get it in and get a chance to shoot with it (the latter of which may take a while since I can't seem to get rifle time in too often lately)
I've decided to scrap the idea I had for suppressing the Puma since it's obviously not as reliable as I'd like for enjoyable plinking and the work to get it both reliable and set up for the suppressor would be extensive and expensive. Now I'm toying with the idea of suppressing my AR. The AR is already threaded and can be suppressed by either threading directly onto the barrel or by using a quick-detachable flash hider. Right now I'm leaning toward the YHM Stainless Phantom. It's rated for full-auto fire as well as being made from stainless steel which should make it more durable as well as being easier to clean. It looks like it retails for about $460 for direct barrel mounting or $535 for the QD flash hider mount option. And, of course, the $200 government-mandated
Anyone have suggestions for which mounting option to use? I doubt I'll be using the rifle for hunting, which is the only reason I can think of for removing the suppressor. But it might be nice to be able to take the suppressor off without resorting to using an upper receiver vise.
