Osprey Carbine Piston on a 607 retro

First would it fit under the triangular hand guard ? Second would it insure a more reliable platform ? Third would I have have a larger gas hole on the barrel for it to run flawlessly ? Please if anyone is experienced with this platform chime in.

Are you having reliability problems?

There is nothing wrong with direct gas impingement.

Actually haven't built it yet, was inquiring because between the cost of a slick side bolt carrier and some other stuff would it would cost a little bit more for an Osprey Carbine Piston set up and was wondering if it was even worth doing.

If you actually have a 607 I would NOT destroy it's value by altering it.

Get a piston if you really want a piston. You won't be improving reliability or function.

Outside of a a very small minority (SBR and supressors) the DI gas is all you need (its been around for 50 years now). I've dabbled with the gas pistons and am unconvinced that anyone really needs it.

If the idea is that "I'll get a gas piston to make my rifle failure-proof.." then this is a mistaken concept. Bad ammo, magazines and other parts will fail your rifle whether
piston or DI.

As for ease of maintenance I have found a love for plated bolt carrier group like nickel boron or MP3. Being able to simply wipe off carbon is like...a god-send!

Agreed...all good points.

I got a couple of piston ARs just to try them out...they are nice to clean (or not have to) but I wouldn't say they are any more reliable than good old DI.

Google "Filthy 14"; she has an impressive performance record that any piston would be hard pressed to match/surpass.

no, unless f/a +sbr

please don't dick w/ the 607

The Osprey system won't fit under M16A2 handguards so I doubt it will fit under A1 triangular handguards.

The Osprey system does not modify the rifle in any permanent way so installation is not "dicking" with it. Watch their video, it's that simple.

Stan, in the interest of fairness I currently have a complete FailZero nickel boron BCG as well as having had chrome bolts/BCG's in the past. While they do make cleaning easier that baked on carbon doesn't just "simply wipe off". There is a little elbow grease required, albeit less than parked ones. Something about those high firing temps bakes that shit to *nearly* impervious to just about any solvent, US cleaner, or plating technology. I have long been in search of the ultimate cleaning tool/solvent/plating and haven't found it yet. Some do indeed make for less work but nothing just makes it "wipe off" completely.

One thing I'll say about chrome or nickel boron BCG's is that you can see the carbon and where you need to get to. Kinda like those little red pills you chewed as a kid to show up the spots you missed while brushing your teeth!

Actually, Chuck, there is a way to modify triangular A1 handguards. The guy at Osprey explained it over the phone to me some time ago when I was contemplating it (never did). Unfortunately I don't remember exactly what had to be done. A quick call to Osprey should answer it though.

Let me begin by STATING THIS IS A RETRO BUILD. That is all.

No, it's not.

I'm thinking WHY NOT, CAUSE YOU WON'T SEE THE PISTON UNDER THE HANDGUARD. GUESS I CAN't BUILD IT.
