P.E. Kelley Posted October 26, 2014 Share Posted October 26, 2014 I was sent this prototype to offer my feedback on. A couple changes were made and I think it is a nice very well thought out unit. Link to comment Share on other sites More sharing options...
cheers623 Posted October 26, 2014 Share Posted October 26, 2014 Awesome piece of maintenance gear! Thanks for the headsup! Will the upper receiver block hold an AR receiver secure enough to remove and install barrels, free-float tubes, etc with just the pins? Or should I still be using a clamping style vice block for that? Cheers623 DVC Link to comment Share on other sites More sharing options...
P.E. Kelley Posted October 26, 2014 Author Share Posted October 26, 2014 Maybe I have been doing it wrong but I use the pin style for the operations you mentioned. Never seen or had any kind of issue, but then again maybe I have been just lucky, and I have had some very heavily torqued barrel nuts to remove! FYI the block in the video fits tight enough that the force is not just on the pins but it is shared with the bottom surface of the upper. Now that does depend on the upper's dimensions.

mpom Posted October 26, 2014 Share Posted October 26, 2014 Looks like its ready for prime time. A bit expensive, but considering its machined from quality aluminum and hard coat anodized, rather than polymer, not unexpected. http://www.crosstac.com/shop-all-products/modular-maintenance-block-kit/ Link to comment Share on other sites More sharing options...
JPeel Posted October 26, 2014 Share Posted October 26, 2014 (edited) Ordered mine after I saw your video Mr Kelley! Looks like a really good product. Edited October 26, 2014 by JPeel Link to comment Share on other sites More sharing options...

CJW Posted October 27, 2014 Share Posted October 27, 2014 Damn, I didn't need to spend that money. Just ordered it, and threw in the cool armorer's mat, too. Link to comment Share on other sites More sharing options...

Cheers623 DVC I don't like it for barrel installs because when torquing the barrel but your putting all the stress on the takedown pin holes. IMO. I have a full cage one for that Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

Cheers623 DVC I don't like it for barrel installs because when torquing the barrel but your putting all the stress on the takedown pin holes. IMO. I have a full cage one for that Sent from my iPhone using Tapatalk I understand your thinking but I have removed many a stubborn barrel nut with way more force that should be needed and have yet to injure an upper. So tight in fact that I bent barrel wrench pins, but again no damage to the upper. (I was concerned in that case to I checked for square on my mill table and a dial indicator) The advantage is this will fit ALL uppers. The "cage" type won't fit the DPMS lo-pro uppers among some other oddballs. Since I work on whatever come across my bench I need best quality tools and fixtures that fit and function with everything.

mpom Posted October 29, 2014 Share Posted October 29, 2014 Patrick, Do you think anything is gained by using this: http://www.brownells.com/gunsmith-tools-supplies/rifle-tools/barrel-tools/ar-15-m16-308-ar-barrel-extension-torque-tools-prod27452.aspx I attach a 1/2" breaker bar to the end, place breaker bar in a vise so this tool and upper are horizontal. Works on all uppers and no fear of tweaking upper. Useful for replacing muzzle devices as well as barrels. Link to comment Share on other sites More sharing options...

I see the merit in that method but Tens of Thousands successful builds have been done with an upper vise block. Link to comment Share on other sites More sharing options...
