Good, Solid Product (17/08/2009)

I just finished a DCM style build using this tube / handguard. The unit is solid and well made with clean threads and a precise fit. It does not come with Delta Ring, Weld Spring or Snap ring. Beware of using the proper loctite as I used the wrong stuff and almost had a misaligned tube that I could not break loose. Fortunately I have access to a good shop with a pipe vise and got it broke lose with no damage. You will have to cut the sling swivel mounts off the standard front sight base and refinish the cut area. I would buy the unit again. I would not attempt to install it without the recommended tools, you will need a spanner wrench and barrel nut wrench that will clear the larger barrel nut.

Excellent product (09/01/2011)

I like the "stock" look of the AR-15 rails, but wanted a free floated tube for service rifle.

This product delivers.

very nice product (15/11/2011)

Ordered this on a Sunday and was at my door Wednesday, Brownells shipped fast ! The unit itself came well packaged and complete. I have no complaints at all. Much cheaper in price than other sellers.

Great Value! Great Product! (18/02/2013)

This free float sleeve is priced better than anywhere else on the web! Dont be fooled this should be named free float sleeve KIT! It is not super clear in the description but this is the whole package, The sling mount, barrel nut, float tube, lock washer, new hand guard (injection molded i believe) Gas tube, Everything you need to do the conversion! Brownells should make that clearer but I still love them. You'll need some tools to do this #1 ACTION BLOCK! dont try to do this without the receiver PROPERLY secured. You need an armorers wrench, snap ring pliers for disassembling the delta ring, 1/16 and 1/8 punches, some loctite, and some Teflon based grease. Some guns will require that you grind off the old sling mount to make room for the new one, so you may want some form of touchup for that. Overall a pretty simple job, took me about an hour (with the right tools.)

Very nice kit. (05/03/2014)

Purchased this for an older Bushmaster AR-15 with a 20" heavy barrel. Had a local gunsmith install it. Looks good and he said it was the nicest free float kit for ARs that he has seen in 30 years of working on them. Looking forward to shooting it this coming weekend. If it shoots as good as it looks, I would highly recommend it.

Barrel nut wrench (13/06/2014)

I bought the Yankee Hill wrench. The hole through the middle of the wrench does not fit over the nut. The wrench needs to be opened up a bit. I called Rock River and they confirmed this. Expect to modify your wrench.

Another Satisfied Customer (03/08/2014)

I bought one of these kits to use with a 22" bull barrel. I'm not a fan of free-float tubes or quad-rail setups, so I got this kit instead.

Unfortunately, the sling swivel interfered with the gas block. But as mentioned above, I'm using a bull barrel. Plus I'm using an aftermarket (not A2 style) gas block. So I removed the sling swivel, and installed one in the handguards.

Also, my mil-spec barrel nut wrench did not fit over the barrel nut. However, I found that the DPMS multi-tool (part number 231-000-007WB) fits both the barrel nut and the lock ring.

All things considered, I'm happy to have a 'normal' looking AR-15 with a free-floated barrel.
