Looking for help on installing a 5C1 Phantom on a Bushmaster M4. Spoke to Bushmaster tech on their 800 line and he says that the XM15-E2S that I purchased about a year ago is pinned and welded at 12 and 6. I think am comfortable removing the POS mini Y that it came with by using a Dremel, any thoughts on proper grinding attachment would be appreciated. My questions are: 1. When installing new Phantom, Can I drill one hole at 6 position to be legal or do I need two pins? One would be easier. 2. What is considered a legal pin? Can I buy one? Can I simply take a piece of cut Coat hanger ? After I remove the Miny Y it might shed some light. But would like suggestions. 3. I own a Gas Wire feed welder. Can I simply pop a spot weld over the Pin and grind it down. Not sure how gun metal works with standard welding equip. 4. I own a vise but not sure how much force will be needed for removal and installation of new Suppressor. Any feedback on how to properly clamp the barrel while I perform this would be great. 5. Is this a waste of time and should I just take it to a qualified gunsmith and have it done right? |
One should be fine.
A solid pin is best - but a roll pin will do. No regulation on the pin's material - just make sure it's strong enough to prevent the Phantom from being unscrewed with a wrench.
Yes
Wood blocks would work - or the aluminum barrel blocks made specifically for the AR-15. Or you could just put the barreled upper into a receiver block...
You sound like you have tools and talent to get the job done. Personally I send mine out to the Pros to get it right (and look great). But if I had your tools & talent I'd do it myself. |

something i learned on the swap i did was to tighten the FS on the barrel first to get your 12 o'clock/6 o'clock marked , then pull it back off to drill the hole/s in the FS. this way when you get the FS tightened back on the barrel , you'll know exactly how deep your drilling into the barrel |
is this a 16" or 14.5" barrel? if it's a 16", you don't need to pin and weld the Phantom. |
