I have been seeing all the new news reguarding comming Piston uppers for ar15 and was wondering if now (or in the near future) was the time to pick one of these up? Is there anything in the pipeline that looks more promising then the new POF stuff? I wouldnt mind holding out if something else looked worthy enough that I should wait consider besides POF.

Thanks

The only problem with the drop in is you can not use off the shelf rails. The guy that built this system is working on one though.

My .02 cents is that POF has been trucking for a over a year so the system is highly reliable.

The drop in system looks good but it's 400 bucks and not available in any numbers so with a good upper and the drop in your still in the 1000 per upper price range.

With the new POF uppers the entire inside of the upper rcvr and charging handle are nickle plated, this makes it an almost a non oiling, no more cleaning upper........

Leitner-Wise has a piston system but the company has had issues.

Colt has a piston system but that has yet to be fielded.

Rumors are spreading that RRA and BM are working on piston systems, we'll see.

AYE! With rra rumor and the lack of colt models to be proven, I am probobly going to wait a little while.

That's a pretty neat piston upper. I'd like to see it when he gets the handguard made.

LWRC, POF USA, HK (yeah right), Colt (maybe), and ARES drop in system are all available. If you want a system they can range from $400 (Ares) to over $1000(LWRC, POF, HK, Colt).
Should you get one? That is up to you to answer. If you're in California you may be better of spending $1000 on OLL's and having more guns rather than 1 nice one.

It looks like this item will be available some time in January as he is OOS at the moment. .

I spoke to him on the tele a few Min's ago. Cost 399.99

He also may have military contracts for this item so it could be a Get it when and while you can item


I found this last night: A "drop in" piston operating system that replaces the standard carbine gas tube. It looks interesting.

No idea on cost or availability.

Interesting adaptation.

I do like that he's thought about wear on upper receiver and puts an insert there.

I have yet to see a real justification (at least for 99.5% of folks, even in .mil) to have a piston upper. I do see poss. reduction in accuracy with stuff possibly moving about while firing.

This just turns your AR into an AK.

I'll have to read thru the ARFCom thread and see what's said about accuracy/reliability.

However, the fact that Denny is playing with it/selling it is a good recommendation. Denny's a very nice guy - who shipped OLLs into CA!! - and is a really sharp boutique AR vendor. If something comes from Denny, it's the best.

[Apparently when you buy something from Denny sometimes you might be in line behind interesting folks from three-letter-agencies etc. Denny doesn't tout this, but other folks seem to think his 'professional' business thrives.]

Oh - this'll be interesting when it's installed on late 90s Bushmasters that had overtorqued bbl installations - where the bbl index pin is bent/partially sheared. This means the opening on the front sight block is not radially aligned with the gas tube opening on the receiver.

This is definately not something I'm concerned with.:rolleyes:

I like the handguard if it's not so thin on top that it will break a lot easier.

The advantage of the piston upper is that it keeps all the powder residue, carbon and gunk out of the bolt area, firing pin, etc.

At a likely trade for inaccuracy.

And dirty ARs - with a bit of proper cleaning - work just fine.

All my ARs are a bit dirty. I CLP 'em with boresnake, brush the chamber, wipe out the upper w/a CLP'd and/or solvent rag, and disassemble/wipe down the bolt + carrier assy. Relube and reassemble.

I can clean an AR in 3 min.

Never a problem, and I'd bet my life on mine.

Does anyone know what sort of accuracy reduction one gets in a piston upper?

No difference in accuracy with this one. I shoot them all equally crappy.
