Gas Piston ARs...

[KBScobravert]

..everyone should convert.

I took my Adams Arms gas piston converted S&W MP15 to the range today and it ran smooth as silk and clean and cool.

The kit was a sinch to install and a blast to shoot.

First order of business today was to clean it since it was still dirty after the last 5-6 outings (my bad!). I applied a very thin film of CLP to the bolt carrier and bolt just to let it slide a little smoother in the upper. I took my laser temp gun to take down some readings. I measured the most rear of the gas block and the front most of the bolt carrier each time.

Before the first round went off the gas block as 63* and the bolt was 62*. After the first magazine of 10 rounds the gas block weighed in at 67* and 91*. As the gas block ramped up to 213* the bolt never got over 87*.

Here is the bolt after 200 rounds the last 60 of which were at a pretty fast rate of fire.


I even ran the suppressor without any cycling issues. It ran just fine. The suppressor got upto 200* after 10 rounds but again the bolt stayed cool at 84*.

The nice part was pulling the bolt and taking a white shirt rag and wiping it off and seeing very little carbon. In fact I think it was only dirty because of the CLP coat I applied.

The gas block never got too hot to handle the front of the handguard. And the test of the polymer flip up front sight went well.

I really had no desire to build another AR15 until I saw all your stuff....

...you bastard! Haha.



My next AR will most definitely be a gas piston gun. Look like that is the way to go.

Maybe an SBR with one of those bumpfire stocks?

There is a reason they call it the Black Rifle Desease.

I got a 416 upper on a trade on a bunch of stuff. I love the way it performed. I traded it off for other stuff, may get another down the line.

Kinda what i was thinking, except going the silenced 9mm route. Id like to get the Gemtech multimount 9mm with a SBR 9mm upper and the slide fire stock

Is the kit just bolt on or is it a little more involved?

The kit is a direct bolt in. Go to youtube and you can see several install videos. If you can remove a front sight base or gas block and install the same you got it licked.

Don't you have a full auto A1? Did you try it out on that lower?

Just got one, waiting on the transfer. The only gun I tried it on was a standard Colt M6700 lower.

Very nice setup. What did the conversion cost you?

[KBScobravert]

Very nice setup. What did the conversion cost you?

I paid $297 for the conversion that comes with standard carbine length two piece plastic handguards. With that kit and a working gun you can go to the range. I chose to get a new bolt (not included with the new bolt carrier) same went for the firing pin, cam and retainer. Those you can always reuse from your gun you already have.

I also opted for a new set of handguards also which increased my costs but I have plenty of ARs to build and can always use the parts elsewhere.

I am taking it to Qual Creek tomorow if you want to check it out.

bleh, quail creek sucks. I hope you don't plan on taking a suppressor or any SBR's.

I drank the piston kool-aid and I love it. My LWRC PSD is by far my favorite weapon.
