Ok this is what I had in mind....take a postban 20inch barrel, cut it to 18inch and thread. Daniel Defense 12.0. Flattop with an ACOG. This is going on a bushmaster lower with a KAC 2 stage trigger. Now my questions... Gasblock. I want the gas block to be a shaved one. WIll the DD hide it or will it be just at the end? What is the best gas block to use in this situation? If it does show then I guess something like the PRI with the flip up front site would be the best. Barrel...will cutting the barrel affect anything? I am probably gonna send it out to ADCO and have them do it professionally. ANything else you guys can think of? I figured I could pick up a postban 20inch barrel on the cheap right now and save some cash. Ranges I will be shooting at will be no more then 300 yards, and using mostly 22grn m193 with some black hills heavier stuff thrown in. |
Nice set up, i would take to the RR two stage or Chip McCormick trigger, it saves you some money instead of the KAC. But KAC is consider as the best two stage on the market.
PRI block will fit right under the DD handguard, it is perfect for your purpose.
By cutting the 20 to an 18, you will not adversely effect any thing as far as the gas impluse is concern. make sure you get a professional smith to do the work because once you can the barrel it is importment to crown the muzzle. ADCO is a good coimpany and will do the work right.
Your set up will work great. ACOG TA31, 18 inch barrel free float handguard, you will get nice group out to 500m. |
On a standard 20inch barrel using the standard FSB location, your gas block will be on the outside of the rail handguard. it will have to be a carbine or mid range setup to get your gas block on the inside of the 12inch rifle handguard. |
| If you want an SPRish appearance (that's what it seems you're going for), then the PRI front flip-up sight would do the trick too. The best part is, it will probably cost you less than a rail mounted front sight with a PRI low-profile gas block and look much cleaner (at least in my opinion). For 500 yards, you might want to consider a scope instead of an ACOG. Nothing against the ACOG, you just can get more magnification out of a normal scope. For $400, you can pick up a Bushnell 4200 series, get a true SPR scope with Leupold Mark 4 for around $850, or spend more than your gun's worth and get a Nightforce, US Optics, Zeiss, etc. |
