survivalshop Posted January 19, 2012 Report Posted January 19, 2012 I got two Tactical Machining uppers in yesterday & campared them to the DSA one I got a couple of weeks ago & can't really tell much difference , except the TM has white numbers on the top rail & the DSA doesn't have them colored & the DSA has a six ( 6) or nine ( 9) depends on how you look at the upper , on the lug for the disassembly pin .The TM looks like it has the lube on the inside of the upper , can't tell if the DSA upper does . They are both nice uppers ,but if I ordered another it would be the TM , because of the whited numbers . Could not find any marks or machine work on them , they look nice .They make a 300 Blackout marked lower , that I want & will get shortly , when I can find time to drive the hour or so down there & may ask for a tour . I mentioned the lower in the 300BLK section .
survivalshop Posted January 22, 2012 Author Report Posted January 22, 2012 I took one of the TM uppers & replaced the A2 on my preban Oly. . That A2 upper was on this 24" barreled 5.56 with one of first FF hands guards that came out of Olympic Arms & it came right off with no problem .Been one there at least twenty years, came right off .I have to find a scope for my new Varmint rifle . This is new territory for me & this rifle ,one of my first builds.Check the markings on that bolt , if you can see them .

survivalshop Posted January 23, 2012 Author Report Posted January 23, 2012 You mean the MP?Yep , first I noticed it . I used M 16 surplus BCG's, on all my builds back then .
imschur Posted January 23, 2012 Report Posted January 23, 2012 I bought a few barrels and bolts from Rainier where I selected the magnetic particle option. I thought"How will I know?" well low and behold they are stamped as such.
