All of those gas piston guns out there….

There are many guns popping up that are now piston driven, everything from Ruger, Adams, POF, and many more.  One of the best levels of advice I’ve given to people when they ask about a certain firearm is to not be the first  one to buy it because you’ll be the first one that has to send your gun back when they find out there is a design flaw or an upgrade.  This happened with the Beretta 92F and we ended up with the Beretta 92FS, and even the LWRC M6A1 had some major internal changes after the gun was first fielded and this is considered the Cadillac of AR15 piston driven guns.

We’ve sold a lot of the LWRC M6A2 guns in the last year or so because they still are the kings of the piston guns.   Recently we’ve also sold a  lot of the Adams gas piston upper receivers which are different in design but I can’t tell you which is better or if they are worth what they are selling for until they have been fielded and  used on the ranges  long enough.   I’ve seen many minor issues with guns from spring flaws, weak pistons, making the bolt carrier group a one piece and eliminating the screws that keep the gas key in place.  These were sheering off on the guns after a  few thousand rounds but anyone that purchased these about 2yrs after they came out got the better version.

Gas Piston Systems what’s the difference?

I’ll write this blog as the biggest non-expert on the topic,  I know what POF and AR18s are like in comparison to LWRC guns but after that, I have no idea what all of these new piston guns from Ruger, Adams and other are like internally.  It’ll take awhile to have to go through the specifications on them or a tall coffee and a couple hours of watching Youtube video clips.  Some of the reviews are really well done, but takes almost as long to find a good review about a product as it does to comprehend all of the minor differences.  I;ll never forget the time it took me to realize that the terms “hook and loop” closure meant velcro on shirts.

The Metallurgy in making bolt carriers, and barrels has changed so dramatically in the last 7yrs, that I seriously need a refresher course before I can even talk about firearm differences. We have a huge number of backorders for the Adams Upper receivers but I have not had the time to actually take one out and compare it to my LWRC stuff.   I think the only thing I can say about the less expensive piston guns is that the designs may be similar, but I would have to say if saving $300 on an  upper for a proven design means saving anything.

AR15 upper receivers sold out

I guess the less expensive stuff is what most people seem to go for and right now that is everything from Spikes Tactical.  The funny thing is these guns are so well made for the price that they were in high demand even before things heated up in the Country.  The AR15 is the primary firearm in the United States and transitioning from Civilian to Military with it is an easy step.  Many people forget that the original intent of having an armed population is so that the population could be called to arms at any moment to defend their Country.

Now that so many people own the AR15 changing the guns to something longer or shorter or to MOE can be as easy as pushing 2 pins out.  There are definitely some big differences in the durability of the firearms, but the lower end of the spectrum for AR15 upper receivers is pretty darn good.   Mismatched parts and bad assemble isn’t something I heard about too often anymore.   The poorly run companies seem to have been cleaned out and there are some really good guns being made.  We’ve sold lots of gas piston AR15s this year and the pool is getting competive.

Gas piston guns, are you going to get a good one for under $1000?

I have some very wise friends and when we first started to see the piston driven AR15s show up on the market “again” about 7yrs ago, it was mostly debates about the AR18, the LWRC piston driven firearms and the POF guns.   I think POF did a good job of staying in the market up until about 2yrs ago.   Now everyone and their dog is making one but I would still caution anyone from jumping in the fire and expecting theirs to be up to what LWRC is making.   The only argument you can make against LWRC guns is probable the H&K 416 variants.

Even with some of the earlier LWRC M6 rifles, there have been some changes, modifications and uprgrades.  I was fortunate enough to have been able to go to the LWRC factory and upgrade on of my LWRC AR15 upper receivers and get the new bolt carrier group without any altering of the firearm I have.  My LWRC M6A2 is a much older version compared to what is out now the barrel life is about 4x’s more.   There are still large variations in piston driven uppers and I got to shoot a Ruger 556 last year and was very impressed with the quality of the firearm, there may be more choices in 2012 and many of them look nice, but will there be modifications or changes to them and getting parts for yours might become harder and harder in 2-3yrs.

Lots of people wondering what happened to the LWRC M6AK

We sold off the last of the M6AK rifles a few months ago but people are still calling and asking about them.  I remember being in the LWRC facility a few years ago and it was just at the beginning of the product run.  I was told second hand that the M6AK rifle was made of left over parts from the other M6 rifles and it was a one off product thing.   I have seen a lot of the Smith & Wesson 5.45×39 uppers go out the door with very few complaints, but I never thought it was a great idea to make a gun in 5.45×39 that was a direct impingement gun.  Just too damn dirty if you ask me.

The LWRC guns were all sold out and gone about a year and half after production and that was it.  As far as AR15 complete upper receivers,   The Adams 5.45×39 seems to be the next hot seller.   You will have to replace the spring in your lower so expect to designate a lower for this caliber.  It’s not a good idea to be lazy and not replace the hammer spring on your firearm. The great thing about AR15 uppers is how interchangeable they are but once you get into caliber variations, you probable want to just get another gun.
