For Smoother, Cooler Operation, Reduced Recoil, & Less Frequent Cleaning

Drop-in gas piston conversion kit installs in only five minutes and improves the reliability and function of your AR-15 by eliminating fouling caused by gas venting into the receiver. Rifle runs cooler, with less frequent need for cleaning and less wear on carrier and bolt - resulting in longer service life from these critical parts. The unique, kidney-shaped cross-section of the piston and piston chamber provides extra mass and surface area to evenly spread out gas pressure and reduce felt recoil, allowing you to stay on target for rapid follow-up shots. Installs in minutes on both semi- or full-auto/burst rifles with a barrel O.D. of .875" or less. No need to remove gas block/sight tower, and no permanent alterations to barrel or upper receiver - reinstall original parts at any time. Replacement bolt carrier with integral lug is machined from a single piece of steel for a lifetime of use. Models available to fit Carbine and Rifle gas systems.

SPECS: Steel, black oxide finish. Handguard – Reinforced polymer composite, black. Kit includes preassembled piston assembly, bolt carrier, handguard, and instructions. Carbine fits 11½" to 16" barrels with .875" O.D. or smaller, and carbine-length gas system. Rifle fits 20" barrels with .875" or smaller O.D. and rifle-length gas system.

Excellent Product (30.03.2010)

I installed this kit on an AR-15 Carbine. It functioned flawlessly. After 100 rounds, the chamber, upper receiver, and bolt were still clean as a whistle. I am a gunsmith and will be recommending this kit to all my AR-15 customers.

Avoid like the Plague (07.06.2010)

[...] when my gunsmith attempted to install the piston on my upper, specifically mating the piston chamber with the front sight tower, the hole in front sight could not be made to aligned with hole in piston chamber tube(The piston chamber bottomed out on the hand guard cap before the holes could align, making it impossible for the role pin to be inserted-obviously a critical measurement not taken into consideration) What's worse the fit is so tight, I haven't been able to remove the piston, so I'm left with a useless upper. To sum up avoid this product like the plague!!!

Amazing (31.08.2010)

Easy Install. Great product! Ran 120 rounds through it and pulled the bolt and it was cool enough to handle. And still practically clean as a whistle. Not but burst a previous reviewers bubble but Osprey and most other Piston conversion websites list hand guards that are compatible with there products. So check that first and either change your hand guard or find a different piston system. Since your adding a piston under the hand guard replacing a very thing gas tube it makes sense there may be space issues with some handguards.

Great system!! (08.11.2010)

System is very easy to install and you don't need to spend another $100 on a new front sight. Liked the fact that it installed into existing gas block. Did not affect accuracy one bit, but did reduce muzzle climb noticably. Reciever/bolt stays very clean and cool to the touch.

#1 piston system (07.01.2011)

fast and simple install, heavy duty components and no valves or adjusting of anything ever, just install and forget. makes cleaning too easy, just wipe down the bolt carrier and re-oil, even the chamber and bolt face seem to stay cleaner. make your accurate AR as reliable as an AK, if you want a piston gun this kit is for you

Broke after 30 rounds (05.03.2011)

Installation is not as simple as stated by manufacturer. As the piston is inserted into the gas block, it bottoms out before the holes for the roll pin aligns. The gas block hole had to be re drilled to get it to fit. Coupling separated from the rod that pushes the bolt carrier after only firing 30 rounds. I checked the rod and the coupling, and they were not threaded, or welded together. The rod was just pressed on. How is it supposed to stay on?

this thing is great! (23.04.2011)

i give it 4 stars because it was a pain to install on a used m4...since the gas and carbon had built up and getting the pins and gas tube out was impossible to do at home.

further more, it gouged up a little section inside my receiver...nothing major but it did happen...

Quality parts (05.06.2011)

I won one from Osprey Defense last summer and have put a thousand rounds through it with no issues. Great product!

Not quite a 4-minute install (18.06.2012)

It works great once you get it installed. The pins that they supply to replace the gas tube roll pin are larger and much more difficult to get into the FSB. I had a YHM railed gas block and scratched the heck out of it trying to drive in the pin (not a roll pin so it's hard to keep a punch on the pin). After lots of banging (and some Birchwood Casey touch-up paint), I got the piston chamber installed.

The other tricky part is getting the clip in place that holds the op rod to the piston.

Also, be sure that your handguards are compatible...Midwest Industries makes some specifically for this kit.

All in all, it was a challenge, but it has performed flawlessly once installed.

Breaks Itself (26.08.2012)

Had mine for a few years now and just removed it last weekend. Put only about 800 to 1000 rounds through it. That "unique, kidney-shaped cross-section of the piston and piston chamber" has very tight clearances. It fills with carbon quickly and looks like if went unoticed, would seize. Have to take the entire system out to clean. Oh and it suffers from that whole Carrier tilt thing. And Finally I noticed that it looks like they havent updated their own site in 2 years. Concerning.

Great product Easy install (01.03.2013)

This product is great! It took me about 20 minutes to install and functions flawlessly. I have both the Adams Arms kit and the Osprey they both work great. I run approximately 500 rounds a month thru this AR and have not had any issues.

Osprey Piston Review (01.07.2013)

I have use Ares, Adam Arms and Osprey piston system for my ARs. This system is great for 7.62x39 cal. The installation took me about 10 minutes. It's really simple and easy. I am not a gunsmith. Yes, There is few bump with Osprey system. The tongue part came loose after 300 rounds. I got a replacement part about a week later. Customer service is awesome. After 8000 rounds later, the system is still running strong. I would recommend this system to others.

great kit but...... (03.02.2014)

This is the second kit I bought. Keep in mind, if you have a free float barrel nut,you will have to contact ospreydefense.com and ask for Izzy, you will need a modified op rod, as I did for my FF Midwest industries rail barrel nut. If you have a standard barrel/star nut, you will be fine.

OPS-416 works great on mil spec. (21.03.2015)

If your AR is Mil-Spec, this kit will work just fine. Commercial ARs will require fitting for gas port & op-rod to line correct. You will need a 5/64" Starter & roll-punch, .072 CUP TIP PUNCH #3 , front sight block, gunsmith-hammer, & cleaning-rod. Also, I recommend a Tapco Armour & Hand-Guard Removal Tool, AB Arms Hand-Guard & a HeavyBuffers.com Anti-Tilt Carbine H1 Buffer w/ Wolff XP action-spring; this will eliminate carrier-tilt. The nice feature of the kit is the piston was designed to be self-adjustable for gas charge, so no adjustment knob on your gas block. In addition, no extra springs was add to this kit, for the op-rod or bolt; adding more reliability to the AR platform. One of the greatest features of this kit is now you can put 6,000 rounds thru your AR before failure-to-cycle occurrence, instead of 600 rounds failure-to-cycle occurrence with the old D.I. systems w/o field-stripping your AR.

Best product on the market (16.10.2016)

This gas piston system is incredible, easy to install, all you need is a pin punch and a rubber mallet. The install was done in 5 minutes, all the people that talk about the tight fit are mounting the piston chamber upside down, ive seen a few try to do it that way, if you follow instructions and take care to do it right it will go in without a problem, i have it installed on 2 guns, one has a standard front sight and another is a low profile gas block. Both instaled without any issues. I am running one as a stress test, its a Bushmaster, with the gas piston being the only thing that was changed from factory build. I put 1000 rounds through it every weekend, i shot it every way possible, slow shooting all the way to even tried the slide fire. Im at 23000 round with no failure so far, i will keep it going until it fails. I am using federal ammo. I highly recommend this system to all my friends that ask about it, I recommend it to you as well.

Thanks Osprey (01.01.2017)

I installed a mid-length system on my 6.8 SPCII build in July 2015. The assembly was easy and the overall appearance turned out nice. The Magpul handguard is what I used to replace Ospreyâs factory handguard. The system works great with hand loads ranging from 90 grain âtacticalsâ to 150 grain âheaviesâ. The rifle performs well with different factory ammo as well. Thanks Opsrpey.

4 years and counting still going strong (26.05.2018)

I installed this 4 years ago since then I've fired thousands of rounds from my weapon. This system has never had a problem I shoot at least once a week, no issues with accuracy or reliability. Only thing I do not like is it is really hard to find hand guards that fit with this piston system, there's a list online if you google it though which will help. I haven't noticed any wear on the piston system or my weapon. If anything ever happens to my system I'll update this review.

Avoid like the Plague (07.06.2010)

poor fit (30.08.2012)

do not buy osprey defense none of the parts fit right; the pin that goes where the gas tube pin was is impossible to get in and the op rod is too long

great product (18.03.2013)

as one other person stated the pin is a little hard to install but after getting it in it will not fall out. I have a colt A2 and with just a small sight adjustment I put 10 rounds in the 10 ring with 7 in the x ring at 100 yards and I have bad eyes

wrong parts in kit,osprey didn't have (12.06.2014)

I will still give it a 2 because of design but be warned my kit had a op rod that was too short and when contacted them they said brownells must have grabbed one that had alternative lengh rod/whatever!
the kit was sealed and said rifle and I said well I need the right rod and they said they didn't have them, they were out.I really like gas but to 1st package wrong then act like it was not their fault then to find they have none with proper length makes me realize they have lost quality control.
The design again is smart,great even and easily fit under a few of my hand guards and easy to clean but instead I had to go with di (it's fine I just hate cleaning all the scum and the heat in my face). I would say get piston from my guns that have it factory but I can't say that until I see kit's working on rifle.

Thanks Osprey (01.01.2017)

great product (06.10.2017)

took me a bit longer to install due to personal mistakes. other than that functions great.
