Brocock Concept Lite is in the house...

It's .22, If you all are interested I'll report on it in a couple days and give a little review... I really like it so far, waiting on some goodies for it, still need to pick a scope for it, I will be playing with an Old Centerpoint scope I have here later, see how it does...

Velocity, 800FPS with JBS 15.9s +- 3 fps Out of the box, no adjustments made by me...

Ken

I may have been incorrect about the pellet weight when the gun was shot through the chronograph at Trenier Outdoors, I think we may have been shooting the heavier JSBs, I just got it home, have only read the manual once...

RE: Folding stock version; my folding stock adapter and Magpul UBR stock along with a Magpul AK47 MOE Rubber Grip will be here this week, mine will be a folding stock version this week, photos to follow...

I purchased a new LDC for this rifle, 0db by Huma, it makes the rifle extremely quiet, although the rifle is very quiet with the stock shroud, the rifle comes stock with a standard 1/2-20 UNF thread on the shroud from the factory... Very pleased so far, I'll report back after shooting some strings through the chronograph with known pellet weights...

OK, the real numbers of my first 10 shot string ever recorded through my Caldwell BP Chronograph...

I'm new to using any chronograph and the Caldwell application, I will find out the numbers I need to plug in to get a better data set and how to better utilize the chronograph... More to come...

Ken

One more string from this morning... Another ten shots, I cannot report on accuracy yet as I have no decent scope to mount on this new rifle, it has an 11mm dovetail rail on top and I have no rings for a 30mm tube... I will have it setup completely in a couple days and will report back often... Here's the second ten shot string through my chronograph...

A little more… The hole pattern on the foregrip of the Concept Lite is the same as M-Lok, but its not actually compatible, the foregrip is threaded directly and uses a little larger fastener than standard M-Lok mounting... Also, the lower piccatinny rail is not removeable as it's machined directly into the aluminum lower receiver housing, it's very well made... A photo... Sorry about the lighting... The large rail is a stock Concept rail, the smaller one is actual M-Lok...



Ken

I'm going to design a set of vinyl wraps for the Concept Lite, I'm going to do it in "Digital Urban Camo" on the lower receiver panels and gas tube, carbon fiber on the barrel shroud and possibly some other accents, I'll post photos when it's done...



The above graphics I cut for Leshiys, but show the pattern I'll be using...

Ken

I have a scope mounted as low as it can be and I think it's fine, the thin buffer tube and adjustable stock provide for a lower cheek weld which aligns with the scope mounted low... Should be fine... I should mention the scope mounted low does not interfere with the magazine or included single shot tray in any way... The adjustable length stock is nice, has no wobble and is solid at every position... These are just my personal opinions...
