Re: Anyone have experience with LWRC, ACRs, or SCARs?
I owned a LWRC M6A3 and couldn't shoot precise groups with it. On another forum - one gets bashed for questioning its accuracy. I had more than a few offline discourse about accuracy issues with discouraged owners. I was getting getting 5 to 7 MOA at 100 yds with many different factory quality ammo (55 to 62 grains). After switching to 69, 75, and 77 grain ammo, it tightened up - but only to 2-3 MOA best. Finally threw my Hensold 4-16 on a bench sandbag once and got 1.5 MOA a <span style="font-style: italic">few </span>times with 77 grain Black Hills. The pundits argued "it's the shooter". (I shoot sub-MOA with another 12.5" brand consistently, so you decide) Tried different ammo for one year, and finally decided I can't afford feeding it only Black Hills 77 grain ammo. (in the end, I tried 15 different ammo) It's not a criticism against their products, I still own and enjoy their 8" PSD in 6.8 SPC: it shoots 1.5 MOA consistently. The 14.7" 556 upper I had was heavier than DI AR's, so it was a bit unwieldy as well. In the end, I respect others that have accurate LWRC AR's, I simply didn't have that luck.
My experience with Scar 16,
Pros: funny looking design but feels great in the hands when shooting, PWS brake loud but minimizes recoil effectively making acquisition easy, side charging handle very efficient, accurate enough (1.5 to 2.0 MOA @ 100 consistently) but <span style="text-decoration: underline">not</span> highly ammo sensitive, folding stock a good design.
Cons: parts have poor availability, had to modify my large collection of PMAG's, heavy (but still handles well), hand hits any mount levers that protrude on same side such as QD lever(reversing to other side solves it), few plastic parts are cheap and break (ie. stock release button), and trigger heavy/gritty and just plain sucks (Geissele Scar trigger costs the same as a used Glock).
No experience with ACR.
Hope that helps, good luck.
