I have an LMT Defender 2000. I want to do some modifications. Im planning on replacing the factory barrel with M4 cuts with a Daniel Defense lightweight barrel and low profile gas block. Im also planning on installing a Larue Tactical 9" forearm and utilizing Troy Industries front and rear flip up BUIS. I have some very specific questions regarding this transformation and the tools necessary.
I have been thinking about this work and have arrived at the following plan. I think I can remove the plastic handguards on my rifle, remove the gas tube pin, pull the gas tube slightly rearward and then foreward around the A2 sight gas block for removal. I think I can then use an AR barrel nut wrench to remove the barrel. Since Im replacing the barrel anyway, I see no need to remove the A2 sight unless this wont work.
I can then replace the barrel and install the Larue forearm according to the instructions provided. Obviously the flip up BUIS wont be an issue.
I can see a need for the following tools: (please give your opinions and advice on exactly what tools are needed and exactly which brand you like best)
a) AR vise (which model / brand is best)
check out home depot, lowes or rona
b) Barrel nut wrench (which brand is best)
DPMS is decent CLICK ON ME
c) punches (what brand is best, brass or steel, what sizes) Y
ou probably only need one brass punch(which you'll most likely not use), the rest should be steel, I have 3 separate sets of punches... the snapon's have yet to bend.
d) strap wrench (anything special??)
you mean a torque wrench?
e) mallet (Brownells has one that is brass on one end and plastic on the other- Looks good)
I have a huge assortment of mallets, hammers. On the AR I only use a leather mallet.
f) gas tube wrench??
you mean a gastube pin punch?
1) Is this something I can do at home?
yes
2) Will the new barrel automatically headspace properly?
it should
3) Can I use the old gas tube and roll pin or should I get a new one?
the old ones will work fine
Any and all recommendations and suggestions welcomed!!
