POLL: Do you use a piston gun as your "primary" or "go-to" rifle?
I would if they were less expensive. I got my LWRC for about $1100. The only two piston guns in that range are AKs or a Kel Tec (won't happen).

I would love to go with the VHS-II that Springfield brought over as the Hellion, but that's about $1k more money and I'd love to go AR or AK pistol for similar size, but I'm going to wait until this round of Biden Dick Fencing is slapped down by the courts. I don't want to SBR and go through that headache.

I answered along the lines of, was it meant to be more of a SHTF gun, yes, definitely piston. If I could only carry 1 for extended times, build-up and cleaning would not be an issue.

I have a rifle that I built for 3-gun comps and I love it. Mostly Bravo company parts with an Adam's Arms Piston set up. This gun runs beautifully and is very fast and 1 MOA accurate with the right ammo. What I love most about the Piston setups is the ease of cleaning. Literally, Just wipe the bolt off---no scraping or scrubbing. Now--the downside: It's a little heavier and it's got more moving parts to fail------to date, no issues on mine but the possibility still exists. Now, as good as this rifle is--it would not be my primary or go to rifle. For me, that would be my budget friendly M&P (gas gun). Its lighter, fairly accurate, very basic--fewer parts to break and easier to manage and shoot and most importantly, it has never failed.

Just my 2cw.

If you want more magazines for it, there does appear to be a decent solution. Not necessarily cheap, but way less than the Finnish magazines go for.

AK Forum polymer magazine adaption thread.

The 3rd listing, 30 round 5.56 Izhmash Saiga magazine.

The Russian Saiga magazines are built like their military magazines, but with a front feed ramp. The metal inserts should make fitting them to the Valmet not drastically weaken them like all polymer Saiga magazines made in the US would. There also isn’t the ribbing like on the US poly mags that has to be removed.

Voted NO, because I don’t have and piston rifles. I was an armorer in the CG and at my department. No need to spend $ on a new system(piston) when my DI carbine works fine. I’m gonna clean it after I shoot it anyway.

I do not. I have probably said this here before. It is a testament to Stoner's design that it works with a piston shoehorned on top of it.

That doesn't mean that piston guns can't run well, but there is an elegant simplicity to the perfectly inline reciprocation of the tail of the bolt as the piston.


I am a big fan of the AR platform, and the ARs that I own have performed nearly flawlessly for me. Including race guns that are tuned to the ragged edge of reliability. I can count on one hand the number of stoppages that I have had on the clock, and I have been able to clear those in mere seconds. This is with roughly 20k of rounds downrange on 3 gun rifles alone.

Super short ARs may function better with a piston because they are so far outside of the design envelope of the original Stoner design.

Voted NO... I got rid of everything but my standard DI AR15's. Had a SCAR and a few other "exotic" rifles but none of them did anything better than the DI AR15... (other than cost more). Additionally the parts for the different systems, IF you can find them, are usually way more expensive.

Not to mention during the inevitable zombie apocalypse, battlefield pick-up M4's can easily be stripped for parts. SmileBig GrinSmile

I used to have a LMT MRP Piston gun as my primary gun. I then bought a LMT MRP DI gun and that's now my primary rifle.

almost kept it

but someone else had deep pockets, and it was in 223,


shot a few in full auto many years ago, wish I had kept one,

Apples-to-apples, when it comes to quality; why did you opt for DI?

Yep, Tavor X-95 with an Aimpoint pro. I run it faster than my AR and it’s my. Home defense rifle, nice and smooth and fun to shoot

Yes. My pws is my go to because it is quieter and less gassy suppressed than my di guns.

Yes...I guess. However I didn't vote with my explanation below.

My preferred piston gun is my PWS Mk114. It's been the antithesis of stereotype overweight piston rifle. Really dig how light it is compared to my 516s and Superlative builds. Its reliability isn't tied to any specific loads and as accurate as anyone might ever hope for with many different types of 5.56/.223. However I also have a "half-breed" DI 16" DD V7 LW upper over a Aero lower that I've been very pleased with how it's been been running. I certainly wouldn't be adverse to the idea of choosing that mixed DI rifle over the piston if it happened to be stacked prominently in front of the PWS in the safe at bug out time.

IME, piston guns are a bit louder than "DI", when using a silencer. I haven't shot a PWS, suppressed or otherwise, but I've shot other long stroke guns with silencers, and have found them to be louder. I have also found, depending on the silencer and system characteristics, that some piston guns are not as clean as think they ought to be either, though they are certainly cleaner than a "DI" would be, with the same round count.

The mcx and lwrc piston guns fit the mold you are describing. PWS does not.

KSGM I have no idea the actual testing you have on DI versus Piston noise while suppressed. I think its just your ears, but maybe you know of actual measured data. If its the latter what is the magnitude? But to put it in context, on the suppressors I use on 5.56 and the different barrel lengths the difference between the best and worst as published is nearly 6 db. And I get tone and all that, but that's a huge difference and its nothing to do with the type of gun. Anyway curious on this mostly. I'm not giving up my SCAR addiction even if its louder...

Indeed it is. The most impressive example I can recall was the same silencer on a 10" AR and a Sig 553 (9"). The Sig was significantly louder. It's got one inch less of barrel, which isn't helping, but it seemed unlikely that the barrel length made all the difference. Could have though.
